Persistent Global Variables

You can save selected NCL global variables to preserve data between restarts of the region. Saved global variables are known as persistent global variables (PGVs). They are automatically loaded at restart.

You can use the GLBLSAVE process macro or calls to the Persistent Global Variables Interface ($CAGLBL) to create PGVs. GLBLSAVE has an NCL procedure ($RMMC47S in the COMMANDS data definition) that shows how to use $CAGLBL.

Note: For more information about $CAGLBL, see the Network Control Language Reference Guide.

You can administer PGVs from the Persistent Global Variables List by entering /PVAR at the command prompt.
