combining multiple columns into one column - enhancements

[markx]

Hello everybody,

Today, I've found (on one of the excel newsgroups) a macro "combining
multiple columns into one column", posted initially (probably) by Dave
Peterson or Bob Phillips.

The macro makes the basic work, however I would need some additional
enhancements:
- my initial page contains formulas, so I would need to convert these data
into "paste special/values".
- I've noticed that when I put "ctrl + down arrow" on the columns, il goes
further than the last cell with value (in fact, it goes always until the row
143), so it should also be resolved somehow... , because without this,
there will be a lot of "free" space between the "real" end of one column and
the start of the next one...
- some columns contain blank cells in the middle: what should I add to the
code (as an option) if I want to elimitate all the blank cells in the new,
combined, column?

Many thanks for your help on this...
Mark
