Edward,
Thank you for the reply. I am in fact storing price in a separate field, however, I need to extract information from a memo field (that is a program generated memo field). So my question still stands as I need to find an occurence of a value with a wildcard within a memo.
If you are aware of using ATC() with a wildcard, please let me know. Or if you know of another function like this.
TIA

I will find the string I am looking for and determine the starting position and length of the substring to return the needed substring. This was working because I assumed a certain character would never be used in the memo field and this character is now being used. Now I want to search for that string with only numeric values following it. For example, I want to extract a price from a memo field that has and '@' sign followed by a space and then some numeric value.
