Specifying a temporary file directory (TMP)

The compiler shell program creates intermediate files as it processes your pro- gram. By default, the shell puts intermediate files in the current directory. How- ever, you can name a specific directory for temporary files by using the TMP environment variable.

Using the TMP environment variable allows use of a RAM disk or other file systems. It also allows you to compile source files from a remote directory with- out writing any files into the directory where the source resides. This is useful for protected directories.

To set the TMP environment variable, use this syntax:

set TMP=pathname

For example, to set up a directory named temp for intermediate files on your hard drive, enter:

set TMP=c:\temp

Resetting defined environment variables

The environment variables that you define remain set until you reboot the sys- tem. If you want to clear an environment variable, use this command:

set variable_name=

For example, to reset the A_DIR environment variable, enter:

set A_DIR=

Verifying that the environment variables are set

To verify that the environment variables are set, open a DOS box and enter:

set

This command lists the path and environment variables and their current values.
