EXEC 2
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.[1]
EXEC 2 is similar to CMS EXEC with the following enhancements:[2]
- There is no 8-byte restriction on token length.[3]
- 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.
XEDIT Macros
XEDIT Macros are files with filetype XEDIT, whose contents are written using the syntax of CMS EXEC, EXEC 2 or REXX.[4] Like regular EXEC 2 "EXEC" command files, they begin with a "&TRACE" statement,[4] to distinguish them from CMS EXEC files.
History
Written in the 1970s,[5], EXEC 2 was preceded by CMS EXEC and superseded by REXX.
All three command interpreters—CMS EXEC, EXEC 2 and REXX — continue to be supported by the IBM CMS product.

gollark: I still don't really care very much if people go around testing... weird brain things... on others, as long as everyone involved agrees to it, licenses or not.
gollark: You can talk here and ping whoever you're replying to.
gollark: You mention near-infrared, which is apparently absorbed somewhat less than other wavelengths by skin and such, but based on my 30 second duckduckgo search it's still scattered and absorbed a decent amount by that and probably is blocked by the skull, which is where the brain is.
