Hi,
I'm using the val function and setting the const _valcheck to 1, which should cause the err variable to be set when the value being converted by val is not a numeric. This works well for almost all cases, except when the string being converted is blank. example
[code:1:dc2247618c]const _valcheck = 1
dim stemp as string * 10
dim btemp as byte
Stemp = "100"
btemp=val(stemp)
Print Stemp ; "=" ; Btemp ; "->" ; Err
Stemp = "xxx"
btemp=val(stemp)
Print Stemp ; "=" ; Btemp ; "->" ; Err
Stemp = ""
btemp=val(stemp)
Print Stemp ; "=" ; Btemp ; "->" ; Err
End[/code:1:dc2247618c]
It's not really a major problem, you just need to check if the numeric returned is not 0 (In my case the value should be >0 and < 1024), but if 0 is a valid value for you then you need to check that the string is not blank and that starts getting really messy.
