finding the wincrt of pascal unit

These units are part of Borland Turbo Pascal for Windows (TPW) or other Pascal-Windows-Compiler like BPW. Borland didnt realase the source code of these units there are pre-compiled TPU - Files avaiable. These files should be in the unit directory of your pascal compiler, a directory like '\UNITS' or '\BIN\UNITS'.
I don't have these files, and to give them out would be against the copyright laws and illegal, but you can try if you find them at www.filez.com

Sorry, but i need the exact location of the files

You need the Bonus Pack that comes with the full Borland Pascal 7 program. It's a sole disk and when you install it it places all the source code in a directory named RTL, and the files you need are places in a directory named WIN under RTL. Or couse if you don't have the Bonus Pack disk (the only extra disk than comes with the program) you will not have the source code. I don't know if all the version of BP comed with the Bonus pack, but I suppose that if you have the original version of BP7 and don't have the Bonus Pack you can ask Borland for it.

Excuse me Noam. But, you rejected my answer because you expect the files or the correct answer?. I have BP7, and I can tell you that the files *are* there.
