How to add a new item into the end of an existing line?

[Jerry Jensen]

Keith,

There is a good explanation of chunk expressions in the User Guide, starting on p. 168.
You get to the User Guide by opening the Resource Center from the toolbar, which has a link 
to download the PDF of the User Guide. There is lots of good stuff in there that explains the basics.

What is in tRecord? It needs to be the line NUMBER, not the contents of that line. 

If tRecords contains:
first line
second line
third line

put comma & "foo" after line 2 of tRecords -- will change tRecords to:
first line
second line,foo
third line

But instead if you put "second line" into tRecord
put comma & "foo" after line tRecord of tRecords -- will fail at runtime
because the variable tRecord doesn't evaluate to a line NUMBER or range of numbers.
It compiles OK because tRecord might contain a number at runtime, it can't tell.

Cheer,
.Jerry
