Hi I've been poking around on the use of Contains, which is what I think I need to use in my fex, however I need to take it a step further. I want to say:

WHERE FLD CONTAINS 'W-' OR 'S-' OR 'C-';

The key is that it has to be the first two character of the field NOT just anywhere in the string. Can anyone tell me how to do that.

Try LIKE instead of CONTAINS:

TABLE FILE CAR
PRINT 
COUNTRY
CAR
MODEL

WHERE COUNTRY LIKE 'EN%' OR COUNTRY LIKE 'FR%' OR COUNTRY LIKE 'IT%'
END

As is frequently the case, there are multiple ways to do this. Francis' suggestion will probably generate the most efficient SQL. You could also say

WHERE EDIT(FLD,'99') EQ 'W-' OR 'S-' OR 'C-';

There is also the fall-back of defining a virtual field that is equal to the first two characters of FLD and then using that virtual field in your WHERE. The problem with that is your selection criteria on a virtual field basically causes a tablescan (if that is your only criteria) because it has to read EVERY record anyway to calculate the virtual field, then throw it away if it does not meet the criteria. Very inefficient.
