I just compiled pascal-s (Moore's iso version, because that's the 
relevant one) but did not run it yet with my patch. It fails at run-time 
or compile-time?
It is an interpreter/p-code system, so has a greater level of freedom.
Note iso7158 is based on Wirth's but Wirth's version is not iso 
compliant.
