Integer. Returns the ASCII value of the first character in string.
Use AscA to test the case of a character or manipulate text and letters.
To find out the case of a character, you can check whether its ASCII value is within the appropriate range.
This expression for a computed field returns the string in code_id if the ASCII value of the first character in code_id is A (65):
If (AscA(code_id) = 65, code_id, "Not a valid code")
This expression for a computed field checks the case of the first character of lname and if it is lowercase, makes it uppercase:
IF (AscA(lname) > 64 AND AscA(lname) < 91, lname, WordCap(lname))
