Hot Tracking a text line in a field

[Terry Judd]

Hi Mark - yes you can do it that way but it really isn't necessary to
'reset' all the lines in the field every time you want to change the
formatting of one. Storing the 'highlighted' line number in a local variable
and just resetting this line before you highlight the new line works just as
well well and is probably more efficient when you have long lists to deal
with.

Regards,

Terry...
