TMP

The TMP environment variable specifies the input and output directory for any temporary work files that the compiler needs. For example:

  set tmp=c:\pli\project\updates

Do not specify a directory that resides on a Local Area Network (LAN). If you are working with large programs, make sure you set this variable to a location with sufficient free space.
