RCL/2004

(RockWorks Command Language)
Preliminary Technical Reference

Last updated 02/09/04/JPR


Contents


Introduction

Almost all of the applications within RockWorks may be accessed, sans RockWorks menus, by placing special commands within an ASCII text file.  The target applications for this capability include;

  1. Users who wish to automate repetitive tasks.  Consider a user who monitors wells around 100+ gas stations.  Every quarter, new lab analyses are entered into the Borehole Manager.  A series of contour maps, cross-sections, fence-diagrams, solid-models, and volumetric analyses are then performed for each site.  The RCL provides a means for automating these processes and eliminating the drudgery of navigating through the menus.
     
  2. Developers of other applications who wish to use RockWorks as a subroutine library.  For example, let's say that a petroleum database software company would like to add contour maps to their product.  They would accomplish this by adding some code to perform the following operations;
     
    • Export data into a RockWorks-compatible format (e.g. ASCII tab-delimited XYZ).
    • Generate an RCL script to define contouring parameters and necessary commands.
    • Launch RockWorks with a command-line parameter that specifies the script-file name.

    The net result would be a contour map on the screen without the normal RockWorks menus.

    Note that it addition to running applications via an RCL script, it is also possible to display the RockWorks sub-menus.  This is often a more suitable way for third-party developers to use the RockWorks capabilities while providing their users with greater flexibility.

Launching The RCL Processor

There are four ways to launch the RCL processor;

  1. Select the Geological Utilities / Util / Compile RCL File option from within RockWorks and enter the name of the RCL script file that is to be processed.  This might be all that User #1 (see above) might ever need.  For User #2, this method is only suitable for de-bugging scripts.
     
  2. Create an RCL file and be sure to save the file with an ".rcl" extension.  Then, use the Windows Explorer program to associate the ".rcl" extension with the RockWorks program.  From now on, whenever you double-click on an RCL file within the Windows Explorer program, that file will be processed by the RCL "engine" within RockWorks.
     
  3. Use the Windows / Start / Run option to launch RockWorks with a command line parameter that specifies the name of the RCL script file.

    Example:  c:\program files\rockware\rw2002.exe "c:\projects\usgs coal\mycommands.rcl"

    Note: Command line parameter must be in enclosed by quotation marks to keep Windows from terminating the command parameter if there's a space in the file path.
     
  4. Execute (via the Windows "Shell") the RockWorks program from within another program.  By adding an RCL script file name to the command line parameter, RockWorks will attempt to process the associated file with the RCL engine.

Note (again): Command line parameter must be in enclosed by quotation marks to keep Windows from terminating the command parameter if there's a space in the file path.

The RCL (RockWorks Command Language) has been completely redesigned.  The previous RockWorks/2002 scheme, based on XML (eXtensible Markup Language), proved to be far too complex for casual use.  This new version consists of simple commands preceded by optional parameters.  Unlike the previous version, which only covered a few operations, the new RCL includes commands for almost every RockWorks application.

Table of Contents


RCL Script File Format

RCL commands are stored within tab or space-delimited ASCII files.  A typical command file consists of a series of "DEFINE" statements followed by an "EXECUTE" command.  The DEFINE statements define the parameters that are used by the associated EXECUTE command.  For example, let's say that you wanted to import an ASCII file into the RockWorks Geological Utilities datasheet.  You would begin by defining the name of the ASCII file that is to be imported and then you would execute the ASCII2ATD import program.

Example:

: Import ASCII data into Geological Utilities datasheet
: and create contour map.

DEFINE:  ASCII2ATD INPUT_FILE XYZ.txt
EXECUTE: ASCII2ATD

: Create contour map.

DEFINE:  EZMAP   X_COLUMN     1
DEFINE:  EZMAP   Y_COLUMN     2
DEFINE:  EZMAP   Z_COLUMN     3
DEFINE:  GENERAL 2D_OUTPUT    EZMAP.RKW
EXECUTE: EZMAP

All RCL commands must include a colon as the last character.

Examples:

DEFINE ASCII2ATD INPUT_FILE XYZ.txt <--- BAD (No colon after "DEFINE")
DEFINE: ASCII2ATD INPUT_FILE XYZ.txt <--- GOOD (Colon after "DEFINE")

Adding Comments

Blank lines and lines that begin with a colon in the first column are ignored by the RCL engine.  Comment lines are therefore preceded by a colon.

Example:

: Import Data Into Datasheet.

DEFINE:  ASCII2ATD INPUT_FILE ASCII XYZ.txt
DEFINE:  ASCII2ATD INCLUDES_HEADER  False
EXECUTE: ASCII2ATD

: Create EZ-Map.

DEFINE:  EZMAP   X_COLUMN  1
DEFINE:  EZMAP   Y_COLUMN  2
DEFINE:  EZMAP   Z_COLUMN  3
DEFINE:  GENERAL 2D_OUTPUT EZMAP.RKW
EXECUTE: EZMAP

: Convert EZ-Map To WMF Format.

DEFINE:  RP2D_WMF INPUT_FILE  EZMAP.RKW
DEFINE:  RP2D_WMF OUTPUT_FILE EZMAP.WMF
EXECUTE: RP2D_WMF

: Terminate RockWorks.

Examples

The RockWorks tutorial folder (My Documents/RockWorks2004/Samples) include several sample RCL script files that are designed to be used in conjunction within the other tutorial files.  Please have a look at one of these files in order to get a feel for what an RCL file looks like.


Creating 2-D & 3-D Diagrams

Creating Two-Dimensional Diagrams

Before executing any procedure that creates two-dimensional diagrams, you must specify the name for the output (RKW graphic) file.  Otherwise,  RockWorks will leave the file name in an "undefined" state thereby producing an error .  This is accomplished by setting the GENERAL,2D_OUTPUT variable;

Example:

DEFINE:  2D_STRUCTURE STRAT_UNIT 1
DEFINE:  2D_STRUCTURE GRID_NAME  Structure01.grd
DEFINE:  GENERAL      2D_OUTPUT  Structure01.rkw <---
EXECUTE: 2D_STRUCTURE

Creating Three-Dimensional Diagrams

Before executing any procedure that creates three-dimensional diagrams, you must specify the name for the output (XML graphic) file.  Otherwise,  RockWorks will leave the file name in an "undefined" state thereby producing an error .  This is accomplished by setting the GENERAL,3D_OUTPUT variable;

Example:

DEFINE: GENERAL 3D_OUTPUT Stratigraphy Logs.xml <---
EXECUTE: LOG_FENCE

Table of Contents


Enabling & Disabling Diagram Display

Let's say that you want RockWorks to create a two-dimensional diagram but you don't necessarily want the user to see it (e.g. you intend to overlay the diagram later on with another diagram or you want to export the diagram to a bitmap format and then import it into your program).  This can be accomplished by disabling the automatic display within RockPlot/2D via the GENERAL,2D_DISPLAY setting;

Example:

DEFINE: GENERAL 2D_DISPLAY False

In a similar fashion, the automatic display of three-dimensional diagrams may also be supressed viat the GENERAL,3D_DISPLAY setting.

Example:

DEFINE: GENERAL 3D_DISPLAY False

Troubleshooting

RockWorks Execution Log

RockWorks maintains an execution history file that lists various information that may be useful when trying to troubleshoot problems. We typically use this file when trying to diagnose a user problem. The log file is stored within the My Documents \ RockWorks2004 \ System folder. The file is named "RW_LOG.TXT". A new version of this file is created every time the program is launched.

Table of Contents


Sample RCL Files

During installation, the RockWorks program creates a folder titled "My Documents\RockWorks2004\Samples).  The folder includes the following sample RCL files that designed to be used in conjunction within the other tutorial files.  The sample RCL files are a great place to start learning RCL by example.

Questions & Answers

Question: How can I quickly determine a variable name?

Answer: When viewing a sub-menu, right-clicking on a menu item will present a dialog box that lists the group name and the item name.

In the preceding example, we see that the strip log manual depth label interval has a group name of "LOG" and an item name of "DEPTHBAR_INTERVAL".  If we wanted to change this setting within an RCL file, we would enter the following text;

DEFINE: LOG DEPTHBAR_INTERVAL 5.0

Table of Contents


Question: Can I display a selected RockWorks menu in order to avoid recreating my own version of the menu?

Answer:  Yes.  The "MENU:" command will activate a RockWorks tree-style sub-menu without displaying the main RockWorks menu.

Table of Contents


Question: Do I need to define every variable when creating RCL scripts?

Answer:  No.  You should define only the variables that you want to change.  This is important because some applications have over 600 variables.   We've tried to make good defaults settings, so that you won't need to change too much stuff.  For example, you may need to specify which data column contains the geophysical log that you want to plot within a borehole diagram, but you shouldn't need to specify what color and line-style to use for the curve.

Table of Contents


Question: How can I generate a list of variables for a given menu?

Answer:  Select the View / General-Preferences menu and check the box labeled "Create Menu Summaries" and the sub-item labeled "Show Variable Names". 

From now on, whenever you select the "Ok" option from a menu, RockWorks will create a text report of all the menu prompts, current settings, group names, and item names.  The program will load this program into the Windows text editor so that you can use it as a reference for which variables you might wish to change.

Table of Contents


Question: What type of delimiter is used to separate fields within RCL files?

Answer:  RCL files may contain either tabs or spaces as delimiters.  This may seem odd, given that the RCL supports international numeric formats which may contain spaces as digit separators.  Fortunately, this is not a problem because the last item on a given line is always interpreted as the value.  For example, consider the following line of text in which the number (one million) is expressed in a Russian format using spaces for delimiters and a comma for the decimal place. 

DEFINE: LOG SCALE 1 000 000,00

The program processes this line by reading everything up to the first colon ("DEFINE:").  It then reads the group name ("LOG") and the item name ("SCALE").  Next, it looks up the variable type in a table and determines that the following variable is a real number.  Next, the program removes the leading and trailing spaces from the remaining text ("1 000 000,00").  Finally, it uses the Windows regional settings to convert the text to a real number.

The main reason for supporting space delimiters is readability.  Hand-typed, tab-delimited files look ugly.

Question: How do I know where the RockWorks/2004 program is located so that I can launch it from my own program?

Answer:  The program path (i.e. where the program resides) and the user folder (i.e. where the program tables and temporary files are stored) are listed within the Windows registry.  This provides a means for developers of other software to know where to look when launching RCL (RockWorks Command Language) scripts and where to store temporary files.

The registry path for the RockWorks program is; HKEY_LOCAL_MACHINE / SOFTWARE / RockWare / RockWorks2004 / FilePath

The registry path for the UserFolder (the place where we store user-modifiable program tables) is HKEY_LOCAL_MACHINE / SOFTWARE / RockWare / RockWorks2004 / UserFolder.
