I am adding code to an assembly language code base of about one million lines. I want to write some C code that will be used as subroutines to the assemble code. My question is how to tell C what the CS and DS segments are. Thanks, Glenn Boozer Lee Data Corp, Networking Div. {decwrl|pyramid|ames}!mips!leedat!boozer

You need to look at pages 90-94 of the Microsoft Mixed Language Programming Guide (comes MS Macro Assembler 5.1) - "Calling High-Level Languages from Assembly". They suggest starting in C, to guarantee any C initialization code is executed, then calling your assembly code, which can then call C modules ... It also looks like you will have to use the default MS 'language' (Pascal/ Basic/C) segments. I can't reproduce the table they show, here, but you could always use the /Fa option to see what your C routine expects the segments to be called ... Mike Finegan mfinegan@uceng.UC.EDU
