Specifying Access to String Literals
To place strings into read/write memory, you must place the #pragma strings directive before any C or C++ code in a file.
If you use the READONLY option, you specify that the compiler may place strings into read-only memory.
If you use the WRITEABLE option, you specify that the compiler must place strings into writeable memory. Strings are writeable by default.
C strings are read/write by default.
C++ strings are read only by default.
Note: This pragma will override the *STRDONLY option on the Create
Module or Create Bound Program commands.
For the syntax of the #pragma strings directive, see the ILE C/C++ Compiler Reference.
