ploticus: available variables

## available variables | Welcome Gallery Handbook |
| Manual page for available_variables(PL)

## DESCRIPTION

Ploticus scripts may contain variables.`` These variables may be set within the script or by the user on the command line. See variables

This page describes many of the variables that are automatically declared and set by ploticus at run time. These may be accessed by your scripts if necessary.`` These variables may be referenced beginning with the proc following the setting proc. Ploticus is not affected if you #declare or #set them or use these names for other purposes.``

Note that in order to reference a variable immediately after the proc which set it, #proc endproc must be used.``

It is possible that there are recently added variables that are not summarized here; please check the proc man page for complete information.``
