This amounts to a sin. Hardcoded literals are against Niklaus Wirth school of programming. I have picked relevant citations from The Gospel. Why is the community disregarding The Gospel?

This should be:
CONST GLOBLIMIT = 0FFFFH;  (*or GlobLimit, MaxVar, or any good and descriptive name*)

IF varsize + strx > GLOBLIMIT THEN ORS.Mark("too many globals") END;

Shall we ever learn from Niklaus Wirth?
