But the main reason for writing is to give you an update to some 
software I submitted quite a few years ago, called temptab.  I 
originally wrote it in 4GL, but have needed it since at a couple of 
customer sites where c4gl wasn't available, so rewrote it in perl.  It 
produces more or less the same output, although it now includes a "Max 
Rows" column that shows the theoretical number of rows that could be in 
the temp table while it is building, (based on pages allocated / rows 
per page).  Once the temp table is written, the actual number of rows 
is shown in the old rows column.
