In addition to Jon Guthrie's comments,

WriteFormattedInt("Amount: %d.\n", NumberOfThings[1]);

Is perfectly legit Modula-2, providing someone has written the module for it.

It is just that so many C hackers have been bumbling around for so long that
such procedures exist in C.

If you REALLY WANT variable arg counts in M2, write a parameter-passing module.
I think you'd be crazy to use such an abomination of structure.

Warwick.

DEFINITION MODULE VarArgs;

FROM SYSTEM IMPORT BYTE;

PROCEDURE Push(VAR Arg:ARRAY OF BYTE);
PROCEDURE Pop(VAR Arg:ARRAY OF BYTE);

END VarArgs.

beleuch!  Looks like C.
