A Global variable is a user-defined variable that is placed in the IOA Global Variable database.
%%SET statements in the JCL, and SET VAR or DO SET statements in the job scheduling definition, enable Control-M jobs and SMART Table Entities to define Global variables and place them in the IOA Global Variable database.
However, since %%SET, SET VAR and DO SET statements also define local variables, a distinguishing factor is needed to differentiate Local Variables from Global variables. The distinguishing factor is provided by syntax, which is described in Global Variable Assignment and Syntax.
A Global variable from the IOA Global Variable database can be specified anywhere a local variable can be specified in the JCL or the job scheduling definition (SHOUT, DO SHOUT, SYSOUT, DO SYSOUT, MEMLIB and OVERLIB statements).
