This is the Free Pascal Message Compiler. It compiles a .mc file into a .rc and .msg file which can be compiled by a resource compiler such as windres. For example: fpmc -l 90 -e -v -i test.mc -p -r -m windres -i test.rc -o test.res It also produces a .pp pascal unit which contains constant definitions for any message aliases (SymbolicName) found in the .mc file. The compiler recognizes the following directives in the .mc file: MessageID SymbolicName Language Other directives as defined by Microsoft are not yet supported. The readmsg program reads and dumps a .msg message file to screen. dumpfile produces a hex dump of a file. They were mainly used for debugging. Enjoy ! Michael.
