Code for CALLER.PAS was wroten very fast - so i am ask for leniency.
You are right, ut is good point - fix it for TP5.5.

PS: I am little be stuck in code generation process (problem when label change offset betweet compiler pass) - i am try convert msa2 into single pass assembler. When i solve this trouble in my way - i will be very near to obj generation. This is the reason, why i have no new commits now (nothing ready).

Make DOS great again!
