It's not at all clear from your description what you want to do, but I'll take a guess that you want to compare the TFS-TOTAL-DOLLAR amount to a value of 0001421374.23. If so, then the OMIT condition would be:
where p is the starting position of the field.
S9(10)V99 is a 12-byte ZD field. The decimal point is NOT actually stored internally. So you need to compare it to a constant without the decimal point.
If that's not what you're trying to do, then you need to explain clearly what it is you are trying to do.
