Pascal to C translator
P2c is a tool for translating Pascal programs into C. The input consists of a set of source files in any of the following Pascal dialects HP Pascal, Turbo/UCSD Pascal, DEC VAX Pascal, Oregon Software Pascal/2, Macintosh Programmer’s Workshop Pascal, Sun/Berkeley Pascal, Texas Instruments Pascal, Apollo Domain Pascal. Modula-2 syntax is also supported. Output is a set of .c and .h files that comprise an equivalent program in any of several dialects of C. Output code may be kept machine- and dialect independent, or it may be targeted to a specific machine and compiler. Most reasonable Pascal programs are converted into fully functional C which will compile and run with no further modifications, although p2c sometimes chooses to generate readable code at the expense of absolute generality. P2c endeavors to insert notes and warning messages into the output code to point out areas which may require human intervention. Output code is arranged to be readable and efficient, and to make use of C idioms wherever possible. The main goal of the translation is to produce C files which are pleasant and “natural” enough to be acceptable as the new source files for a program. In a pinch, p2c will also serve as an ad hoc Pascal compiler. The p2cc script makes it easy to use p2c as a compiler.
