Is the first character a letter or a number? (Read 383 times)

	I have an element (part number) that is populated with alpha and numeric characters. I need to check On Form Entry if the part number element starts with a letter or a number. I know I can isolate the first character, but other than checking against each letter in the alphabet, is there a way to check if that first character is a letter or a number? Thanks!

	You can use the SBasic function @Asc() to get the decimal value of the character and then use that to determine what it is. Example: Code Var vChar as Char Var vAscii as Int vChar = @Left(PartNumber, 1) vAscii = @Asc(vChar) If ((vAscii >= 48) and (vAscii <= 57)) Then { Writeln("It's a Number") } Else If ((vAscii >= 65) and (vAscii <= 90)) Then { Writeln("It's an Uppercase Letter") } Else If ((vAscii >= 97) and (vAscii <= 122)) Then { Writeln("It's a Lowercase Letter") } -Ray
