Hello,

I have to find out if a character variable inside is alphanumeric or numeric.
Is there an easy command, that I can use?

Hallo Iris,

I have to find out if a character variable inside is alphanumeric or numeric.

VAL returns the info You are looking for

Msgalert( VAL( "aaa" ) ) = 0
Msgalert( VAL( "111" ) ) = 111

best regards

Hello Uwe,

thank you for your answer.
I have tried with VAL, but this is not the solution.

local cNumber = "1S2673Z"
msginfo(VAL(cNumber)) = 1

I think VAL evaluates cNumber until the first non-numeric character.

Thank you and kind regards

cVar:="a5b"
posrange(chr(48), chr(57), cVar) - 2
