Main frame programming is simply programming a main frame computer instead of programming a PC. The languages used are numerous, but the simpler ones are called fourth-generation. Avoid trying to learn the language which the others are translated into, which is Assembler.What is MAIN FRAME in computer proramming,how to learn this s/w,some websites to study,get tutorials,pdf...?
the only way to learn it is to work in real time. since mainframe servers cost a lot, u can't find any tutorial classes using them. they will use simulated mainframe for training which is next to wastage. however, if u r determined to learn it, u may go for the same.
Main Frame in in not a language it's another way of saying core server.
