Your StrTrim() is good; thank you. But it requires that I specify the number of decimals. And I am trying to figure how to do it for any number.
That is, in my case, I have to SCAN records of a table where the column could have different values (as you see in my example above). And in each row, the numeric value has to be changed to the char; matching exactly.
