Hi John,

1. So, as *BUILD and *APPEND commands are in ROM 15, and, very naughtily,
pass a control block to OSWORD in ROM!, I take it that there a bug in MOS
3.20 and probably up to 3.50.

2. Would you please assist with full working programme listing(s), Jonathan, 
as
I am having all sorts of problems getting the code to work correctly.

With Best wishes,

Raf.
