Sort of an expanded list of "dependencies"... The lazarus IDE can give you this information. It can be that you need the cody package installed, but this is how it works: Click right on the function declaration/implementation, select 'find' and then 'Find identifier references'. The IDE will then show you where a particular function is used. Michael. ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org https://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal

When compiles, you can tell the linker to generate a linker map with the -Xm parameter, and then you can see all the (mangled) names of the referenced symbols (variables, functions, rtti, internally generated constants, ...). I'm sure Delphi can also generate a linker map with that information. Jonas ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org https://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
