Using Elastic COBOL from a Command Line Console – Heirloom Computing

Overview

To use the Elastic COBOL compiler and runtime within a command console, it is necessary to set up your PATH (to locate the compiler) and CLASSPATH (to locate the runtime Java libraries).

Your PATH should look similar to:

$ echo $PATH

[...your other PATH env vars...]:/c/users/bradpitt/Elastic COBOL/plugins/com.heirloomcomputing.ecd.core_YY.MM.DD/elastic_cobol/bin/win64/x86_64

The above is a 64-bti Windows example. If you are on 32-bit Windows or Linux, check the elastic_cobol/bin location for the right path to the compiler.

Your CLASSPATH should look similar to:

$ echo $CLASSPATH

.:/c/users/bradpitt/Elastic COBOL/plugins/com.heirloomcomputing.ecd.core_YY.MM.DD/elastic_cobol/ecobol.jar:/c/users/bradpitt/Elastic COBOL/plugins/com.heirloomcomputing.ecd.core_YY.MM.DD/elastic_cobol/etrans.jar

Once both of these have been setup, you can compile/execute programs from the command line:

$ ls

ShowParams.java   calljava.cbl

$ ecobol calljava.cbl ShowParams.java
