The GCAL environment variable

The environment variable GCAL can hold a set of default options for Gcal (see section Environment Variables). These options are interpreted first at program start-up, and some can be overwritten by explicit command line arguments or values found in a `@file' response file. See section Command line arguments, and section Response file, for further information.

For example:

• for sh:

  GCAL="-i @color -b 3"; export GCAL
  

• for csh:

  setenv GCAL "-i @color -b 3"
  

• for MS-DOS:

  set GCAL=-i @color -b 3
  

On Vax/VMS, the name of the environment variable is GCAL_OPT, to avoid a conflict with the symbol GCAL set for invocation of the program.

For example:

• for VMS:

  define GCAL_OPT "-i @color -b 3"
