NAME

describe-variable - Describe current setting of a variable

SYNOPSIS

describe-variable (C-h v) 

DESCRIPTION

describe-variable describes the current setting of the given variable (%, : and $ variables), returning ERROR if the variable is undefined. If a $ variable is not found then it is tested for an environment variable, i.e.

describe-variable $PATH 

returns your environment $PATH setting. This is the easiest and best way of determining the current platform from within a Macro file.

The returned value of any undefined variable is the string ERROR.
