Don't know if there is a generic function to do this. However in such cases it is easiest to look how FPC's biggest console app (the textmode IDE) does it. > 2.)

It has argument and path length problems (due to shortstrings), use the executeprocess function(s) instead. They are in sysutils. And in general, have a look at tprocess: http://www.freepascal.org/docs-html/fcl/process/index.html http://www.freepascal.org/docs-html/fcl/process/tprocess.html and the fcl-process examples (hopefully) installed with your release. _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
