Something like this should work for that case: type TMyProcedure = procedure; // if the procedures/functions you want to invoke have parameters // use something like this: // // TMyFunction = function(arg1 : type1; arg2 : type2) : result_type; var x : TMyProcedure; begin x := TMyProcedure(0x2c); x; // to invoke it. Or "x()" if you prefer that end. Hth, Thomas ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal

One of our major applications is written in C+ + simply because it is to run in the future on an embedded system as well as the PC. Well the embedded processor has been chosen - the Luminary (TI) ARM-Cortex processor. "Cortex" is a whole family of ARM CPUs. FPC full supports the ARM Cortex "A" family of processor (A8, A9). The Luminary cpu is a Cortex- M3. These only support Thumb and Thumb-2. There is support for Thumb-2 (and in particular the Cortex-M3) in FPC trunk, but I don't know how well-tested or maintained it is (the support was added via third party patches).
