Sometimes I wonder what would happen if when using a CISC type computer, like z, but only using the RISC-like instructions.
I learned to program a PIC microcontroller some years ago. It is a RISC (also Harvard) with about 27 instructions, all very orthogonal, and it took me only an afternoon to learn them all. Nice. I miss playing with such tiny computers. -----Original Message----- From: IBM Mainframe Assembler List [mailto:[email protected]] On Behalf Of Don Higgins Sent: Sunday, July 31, 2011 1:26 PM To: [email protected] Subject: z12 new instructions HLASM - High Level Assembler Silly Mnemonics <G> Do we really need any more opcodes? In college I have a faint recollection of learning that all you need to emulate any computer is less than 10 basic instruction types like L, ST, A, S, C, BC and SIO. So why does the z390 portable mainframe assembler with z196 opcodes now have 1293 opcodes? (see z390\rt\test\testins1.mlc regression test source program which tests assembly of them all).) Time is running out to sign up for SHARE in Orlando and come hear about latest updates for z390, zcobol, and zcics in session 9280 Tuesday, August 9 at 11 AM: http://www.z390.org/SHARE/SHARE_9280_z390_Orlando_080911.pdf Melvyn Maltz and I wil be there and hope to see many of you there.
