topic edited to use the code tags instead of the useless bold

1. Use code tags for your program.
2. We have absolutely no idea what is in TXCOPY, or the TXSTART or TXTERM macros. The TXSTART macro, especially, may have a USING Assembler statement.
3. What label (or labels) got the NO ACTIVE USING message?

[tanu_2302]

TXCOPY,TXSTART,TXERM are all macros. They are not creating errors.
labels that are creating error are- NUM1,NUM2,NUM3,GREAT,HIGH,HIGHEST
