Variable Characteristics

Review these variable characteristics:

• A global variable written to the shared VSAM file can have a local or global scope.
• A local variable has the SMF ID of the local system appended to its variable name to form the complete key of the variable record.
• A shared variable has no SMF ID appended to its name.
• Local variables are intended for a particular system, while shared variables are intended for multiple systems. However, you can use the SMFID keyword to manipulate the variables from any system using the VSAM file.
