Argument	Description
fid	The field ID of the global variable
isNull	Indicates whether the variable is null

A predefined PBNI datatype that corresponds to the PowerBuilder datatype in the method name.

This code gets the value of a global variable of datatype long using its field ID:

fid = session -> GetGlobalVarID("l_gvar");
l_val = session -> GetLongGlobalVar(fid, isNull);
session -> SetLongGlobalVar(fid, l_val + 1);
