Program fails with new firmware, no CAS function.

[Digitaldreams]

To aid learning the programming on this beast I have been playing with anothers program. All was fine before the update, now I instantly get "Bad argument type" and 'info' shows the following segment....

while int > 0 do
rem := irem(int,10);
string := IntToChar(rem) + string ;
int := (int - rem)/10;
end;

Any clues as to why this now fails ?. No sign of the CAS function (as mentioned by Tim) anywhere in the whole program.

Regards
