I want to write a bigger program that actually does something rather just setting some condition code! So you want to learn to program in assembler.
We’ll talk about the operating system, the software installed on a mainframe. Mainframe-Assembler is complex and geeky. In a nutshell, we’ll de-mystify the mainframe.
Here is my Assemble-Listing. Some of you might be convinced, that Mainframe-Assembler is lanyuage extinction. Before the computer can execute your program, the object code called an object deck or simply OBJ has to be run through another process to resolve the addresses where instructions and data will be located.
Unlike Unix system calls, macros are not standardized across operating systems though. Research Once you get confidence, start reading and researching how better to program in assembler.
