How about the flip side of the coin? Does anyone know of C to Pascal translators? -- Herb Poppe NCAR INTERNET: hpoppe@ncar.ucar.edu (303) 497-1296 P.O. Box 3000 CSNET: hpoppe@ncar.CSNET Boulder, CO 80307 UUCP: hpoppe@ncar.UUCP

I'd be very surprised to hear of any, since most C programs cannot be translated into Pascal in any simple way. C's pointers, in particular, are far more powerful than Pascal's and there is no easy way to fake them. -- SVR4: every feature you ever | Henry Spencer at U of Toronto Zoology wanted, and plenty you didn't.| uunet!attcan!utzoo!henry henry@zoo.toronto.edu

I HOPE NOT!, jumping willies! Would you put a lawnmower engine in a Porche ?? PASCAL is somthing that got loose from the lab. YIKKES, bring out the dog catchers. Seriously, if you have a need for it, I think that there may be one out in PC land. Check some local bbs's. I seem to remember that one does exists somewhere out there. m > Cheers Woody

Perhaps you're talking about standard Pascal; Turbo Pascal lets pointers be used almost as loosely as C does. Certainly there's no built in operator to increment one, but it would be very easy to write one: inc(longint(rec_ptr),sizeof(rec)); would come close if you didn't need to worry about crossing segment boundaries. A bigger problem would be the growth in a program if it were translated. Assignments must all be done in separate statements in Pascal (unless you define an assignment function), and Turbo Pascal doesn't support macros the way C does, so they'd all have to be expanded before translation. Of course, the biggest problem of all would be that the Pascal program would end up just as unreadable as the C program it was translated from - even Pascal can't make an ugly program pretty.
