what is HLL ? what is MLL ?

JCL is not really a language, it is more a data definition script.
hence u define your files and call pgms that use thoses files.

does it answer your question ?

Hi,
JCl is not a language like COBOl,PL/I -----. It is used to submit the group of comands together to be run.

HLL means I guess High Level Language. I think JCL can best be explained as a bridge between Application Programming Language like COBOL,EZ etc and OS like MVS.

Hai stargazer123,

JCL is not a HLL or LLL, It's a MLL.

It's better known as an Interpreter and act as an interface b/w your OS and Application Programs.

It's interpreted by your Job entry subsystem. It's primary goals are sheduling the jobs, assigning priorities, Specifying required resources, introducing location, specifying time limits etc...
