See e.g. the CHM package. It has the same problem, the file structure is little endian (since windows), but the package may run on e.g. PowerPC. The routine in the url below is used for that. (in this case ntole, but ntobe if your storage is bigendian) http://www.freepascal.org/docs-html/rtl/system/ntole.html http://www.freepascal.org/docs-html/rtl/system/ntobe.html These routines are afaik inline and a no-op if the endianness is the same. _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
