      I Do Declare!

      When there were no debuggers, I encountered IBM/360 and the Cobol code blew over my face every now and then. My favourite being Decimal Data Error. Whenever it did, it generated a dump. I needed to know how to read assembler, what was a Channel Status Word, a Program Satus Word, difference between accumlator and register etc etc. So yes, I DID NEED TO CARE how computer added A=A+1. Did it do a register to register add or did it use an accumlator. I needed to know the assembler instruction where the program blew, the registers it was trying to operate on, and the values in those registers.
