UNIX/Linux

JCL is the scripting language available on IBM mainframe and it is different between VSE and MVS. It can be replaced using standard UNIX/Linux shells.

VSE JCLs can be migrated using the C shell, while when migrating MVS JCLs both C shell and Korn Shell may be used, depending on the presence of GOTO statements or not.

All the samples in the following pages are written in C Shell.
