[Coco] Call code Syscall

[Bill Pierce]

The call codes have one function each. They are the same as listed in both OS9 & NitrOS9 documentation with the exception that NitrOS9 has a coupe of new calls and some typos were corrected.
Some call codes have different modes, which is determined by how the regs are set. There are clearly explained in both Docs. You must look them up in the "Technical Reference" manual. Both the OS9 & NitrOS9 versions are available in the archives.

HelloI was looking at some old code that was written to run under the Old Tandy Os9 Level 2 and I am trying to figure out where the call code is in the /dd/defs file.Regs.A = 0Regs.Y = 1Regs.B = $84Regs.X = $6401Run Syscall ($8e,regs)Executing $8e and the call code is $84. This location may have several different call codes and I am trying to see all the call codes for this address and what each one does?-- Coco mailing listCoco at maltedmedia.comhttps://pairlist5.pair.net/mailman/listinfo/coco
