EXEC 2

This article is about the scripting language for the VM/CMS operating system. For other uses, see Exec (disambiguation).

EXEC 2 is an interpreted, command procedure control, computer scripting language used by the EXEC 2 Processor supplied with the IBM Virtual Machine/System Product (VM/SP) operating system.

EXEC 2 was preceded by CMS EXEC; EXEC 2 is similar to EXEC with the following enhancements:

• Statements can be up to 255 characters long.
• EXEC 2 can issue commands to subcommand environments as well as CMS and CP.
• EXEC 2 has additional built-in functions.
• EXEC 2 commands may include subroutines and functions.
• EXEC 2 has extra debugging facilities.
• CMS programs can manipulate EXEC 2 variables.

EXEC 2 has been superseded by REXX. All three — CMS EXEC, EXEC 2 and REXX — continue to be supported by the IBM CMS product.
