Add following line to .profile or .cshrc file depending on the shell of that user.

In the Bourne shell add the following line to .profile:

<gtm_dist pathname>/gtmprofile 

In the C shell, add the followign line to .cshrc:

source <gtm_dist pathname>/gtmcshrc

In both cases, specify the required full path name to the directory where GT.M was installed.

This creates the GT.M environment variables (See Procedure 1 for the list of environment variables) and updates that user's system path to include the directory where GT.M is installed.
