I have not heard about any issues with the ICC definitions being Pascal "unfriendly".

If you ever want to override/bypass the type checking between the actual parameter and the formal parameter, you can use an explicit %IMMED, %REF, or %STDESCR as appropriate on the actual parameter.  In that case, the compiler will skip the check and just pass what you specified.  You can even provide more arguments than in the format definition by just using explicit argument mechanisms on the "extra" arguments.
