Hi, first I suggest to start with a plain vanilla approach. A near by line
number is much better than nothing at all. But let's see:

Line number of block creation position.

Original file-name and line-number there in.

;-) How many thousand lines do you enter interactively?

line-number of do but dumping the wrong block (perhaps with line-number of
block definition).
Self modifying/dynamic code creation is always a problem but that's the
same in other languages too... ever tried to get a line-number from your
c++ compiler on this ;-)) Robert
