Runtime environment variables

Several runtime variables are of interest for COBOL programs.

These are the runtime environment variables:

_CEE_ENVFILE
Specifies a file from which to read environment variables.
_CEE_RUNOPTS
Specifies runtime options.
CLASSPATH
Specifies directory paths of Java™ .class files required for an OO application.
COBJVMINITOPTIONS
Specifies Java virtual machine (JVM) options to be used when COBOL initializes a JVM.
_IGZ_SYSOUT
Specifies where to direct DISPLAY output. stdout and stderr are the only allowable values.
LIBPATH
Specifies directory paths of dynamic link libraries.
PATH
Specifies directory paths of executable programs.
STEPLIB
Specifies location of programs that are not in the LNKLST.
