!PVWDATA
This system variable contains the path to a directory where PV-WAVE can write temporary and automatically generated files.
On Windows, it contains the contents of the user's
%APPDATA% environment variable with
'\PV-WAVE' appended.
On UNIX, it contains the user's
$HOME environment variable.
If you change this system variable, it must point to a directory for which the PV-WAVE process has read/write permission.
