EXEC 2
EXEC 2 is an interpreted, command procedure control, computer scripting language used by the EXEC 2 Processor originally supplied with the CMS component of the IBM Virtual Machine/System Product (VM/SP) operating system.Some EXEC statements and predefined variables do not exist in EXEC 2, although in some cases there are analogs.There are some minor differences in some statements and predefined functions.[5] Like regular EXEC 2 "EXEC" command files, they begin with a "&TRACE" statement,[5] to distinguish them from CMS EXEC files.Written in the 1970s[6] and formally introduced for CMS with VM/SP Release 1, EXEC 2 was preceded by CMS EXEC and superseded by REXX.
