I'll surely test it later on, but one more question is important: I read "C-style" as syntactically similar but not necessarily really comaptible to C. Would that work when handing over pascal array data to a dynamic library written in C? I had some hard times regarding dimension order in memory and to make sure the data is stored consecutively when feeding integer and single/double arrays to a .so made in C.

Is it also possible to run abc(b[2..9]); i.e. using a start-index different from 0?

You need to export /tags/release_2_2_0 from the svnbuild repository, copy the documentation and libgdb into it then execute "make go32v2zip". If everything goes well you get an installation program. That has to be tested, i.e. wether it installs correctly, basic programs can be compiled, etc. Daniël ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
