Hello,
can you help me please?
I have to find out if a character variable inside is alphanumeric or numeric.
Is there an easy command, that I can use?
Thank you in advance, kind regards

Hallo Iris,
VAL returns the info You are looking for
Msgalert( VAL( "aaa" ) ) = 0
Msgalert( VAL( "111" ) ) = 111

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
