Hi, I wonder if someone could point out a simple way to do integer to string conversion in SUN Pascal. I generate a number that needs to be part of a filename in : rewrite(textfile,filename); where 'filename' is a string. Right now I can write the integer to a text file and read it back as a string - but that's rather dumb! I have been too used to nice Turbo Pascal features for such things... --Raj Chaudhury UCLA, Solid State Science Center

To convert an integer to a string you'll need a loop, which extracts the digits from the integer. This is achieved by using mod. Then you convert a digit by using chr plus ascii for 0. To control the loop and to extract successive digits you must div the integer until the division produces 0. In order for the conversion to be general, you must also test for the sign. It is easier to convert a non-negative integer, and then augment the sign to the beginning of the string. ...................................................................

The new Pascal standard (Extended Pascal) now has a standard method to do this. You use the WRITESTR builtin routine. For example, var i : integer; s : string(32); begin i := 35; writestr(s,i); writeln(s); end --- John Reagan Digital Equipment Corporation reagan@hiyall.enet.dec.com Disclaimer: The opinions and statements expressed by me are not necessarily those of Digital Equipment Corporation. ---
