Thanks PascalDragon,
The shortstring instead of the rawbytestring solved the problem.
Before asking the forum, I tried string, but in ISO mode the compiler says
goto.p(10,8) Error: Identifier not found "string"
goto.p(10,14) Error: Error in type definition
goto.p(13,14) Error: Can't read or write variables of this type
But fpc accepts rawbytestring and shortstring in ISO mode. Strange.
The command line is one of the examples for binding in the standards document of Extended Pascal.
Greetings,
Wolfgang
