What does COBOL compilers have to do with mainframe jobs ?

Adam, the executable jobs on the mainframe are from generated COBOL source programs; hence the need for a CBL compiler
on the mainframe, eh ?

hi Arnd
Actually wot i wanted 2 know was....why a mainframe job in the first place. I got to know that mainframe job was one of the the three types(Parallel, Server and Mainframe jobs). Is it that these jobs are designed and run on a mainframe? and not on other systems ? I think I got the picture.

Adam_Clone,
The three types of jobs you mentioned, Server / Parallel / Mainframe, were all at one time separate products which have been integrated under the common look-and-feel of DataStage. The underlying technologies remain distinct; Mainframe jobs not only generate COBOL code but the requisite JCL and database connectivity as well. Parallel Extender utilizes generated C code whereas Server uses generated UV/Basic code. None of these three types of jobs are interchangeable.
