Environment Variables

XLISP-STAT uses two DOS environment variables. The first, XLISPLIB can be used to specify the default directory in which XLISP-STAT searches for its startup files. If you set this variable, it must end in a backslash character \. For example, you can set it with a line like
set XLISPLIB=C:\XLISP\LIB\
in your AUTOEXEC.BAT file. If this variable is not set, XLISP-STAT assumes the default directory is the subdirectory XLSLIB of the startup directory.

A second variable is XLISPMONO. If this is set to anything, only a monochrome buffer is allocated for buffered graphics. If this variable is not set, both monochrome and color buffers are allocated if the system has color available. On a 16-color standard VGA display, not allocating the color buffer saves about 150K. It is the only option available for trimming back the memory use of the system.
