Hi All,
I’m looking for some help on complex statements in LCB.
I’m trying to take a script statement like this:
if (char x of tCardNum)*2 > 9 then
Hi Stephen,
Don't forget that LCB is strongly typed. That means that a string isn't
a number, so you can't multiply it!
The expression "char x of tCardNum" evaluates to a string that's one
character long. If "tCardNum" has fewer than "x" characters, then it
throws an error.
If the character is expected to be the string representation of a
number, then you probably want to explicitly convert it to a number:
variable tNum as Number
put (char x of tCardNum) parsed as number into tNum
if 9 < 2 * tNum then
...
end if
