Gregory,
Try this and see if it works.
filter tmpData with "*" & tab & myNumber & tab & "*"
There shouldn't be any need to include the preceding or trailing
tabs, except for the ones directly surrounding the number.

Hello Everyone,
I'm struggling with the filter command. I have tab-delimited data
in a field, where each row has at least 56 columns. I want to
filter the data based on a chosen number in that fourth column, for
example, to return all lines that have a 9 there. The fourth
column only contains a number from 1 to 10. The following handler
works most of the time. I put three wild card expressions, lone
asterisks separated by tabs, to make sure nothing is being picked
up in the first three columns. The tab and asterisk (and it could
be just an *) following myNumber says that it doesn't matter what
is in the columns after the fourth.
put fld "Data" of this card into tmpData
filter tmpData with "*" & tab & "*" & tab & "*" & tab & myNumber &
tab & "*"
The trouble is, the first three wild card expressions are
interpreted by Revolution to include tab characters, which means
that I'm not necessarily filtering the fourth column! If a 9
appears by itself in column 58, then the filter command will pick
it up. Sigh.
I also tried the following, but I don't think I have the regular
expression syntax right.
filter it with "[A-Z0-9]" & tab & "[0-9]" & tab & "[A-Z]" & tab
& myNumber & tab & "*"
I know that my first column always contains five words, two of
which are numbers. I wasn't sure how to represent the four spaces
between the words. The second column is always a seven-digit
number. The third contains first and last names, which will
contain at least two words. This turns up empty.
Any advice would be most appreciated. If I can't get the RegEx
working for me, I know I can resort to a repeat loop and pull out
all lines with myNumber in the fourth item.
Regards,
Gregory
