Setting Up the Code Generation Environment

To set the TMP environment variable, use this syntax:

-For C shells:

setenv TMP ºpathnameº

-For Bourne or Korn shells:

TMP=ºpathnameº export TMP

(Be sure to enclose the directory name within quotes.)

For example, to set up a directory named temp for intermediate files, enter:

-For C shells:

setenv TMP º/tempº

-For Bourne or Korn shells:

TMP=º/tempº export TMP

Reinitializing your shell

When you modify your shell configuration file, you must ensure that the changes are made to your current session. Use one of the following com- mands to reread your system initialization file:

-For C shells:

source ~/.cshrc

-For Bourne or Korn shells: source ~/.profile

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:

-For C shells:

unsetenv variable name

-For Bourne or Korn shells: unset variable name

For example, to reset the A_DIR environment variable, enter one of these commands:

-For C shells: unsetenv A_DIR

-For Bourne or Korn shells: unset A_DIR
