You're right. uchar but no uint. You got my drift. Charles

What's uint? I can't find it in stdint.h. I can however find uint32_t, uint64_t etc which explicitly state the number of bits in the type definition name. I always use the typedefs in stdint.h as a matter of course (cstdint for C++). There's also a __ptr32 definition. The only issue I run into with 64bit C/C++ code is having to deal with assembler service routines that were written for 32bit. And you can't just recompile with a different compiler option to make them 64bit! ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
