GEMPAK Environmental Variables

4.3 GEMPAK Environmental Variables

GEMPAK environment variables are used by GEMPAK to find needed executable, table, parameter, error, help, and map files without requiring user input. In addition, environment variables save you some typing in your everyday usage of GEMPAK.

Here are a few of the GEMPAK environmental variables that are set in the GEMPAK environment

$NAWIPS

$GEMPAK - Directory for the top of the GEMPAK tree

$GEMDATA - Location of data files

$GEMLIB - Library directory (used for installation)

$GEMEXE - Location of executable code

$GEMPDF - Location of parameter definition files

$GEMTBL - Location of tables

$GEMERR - Location of error messages

$GEMHLP - Location of on-line help files

$GEMMAPS - Location of map files

In addition to GEMPAK environmental variables you may also reference your own environmental variables from your user shell within the user interface.
