Input 2 digit numbers

[Clark]

Could you give me an example of when you would want to use the "val()" function with a numeric string? Wouldn't this be completely pointless?

It's often wise to get user-input as a string, and then parse that string to numbers/symbols/text/whatever.

Without local echo:

Code:

1 PRINT "Enter a two digit number: ";
2 k$ = INPUT$(1)
3 IF k$ < "0" OR k$ > "9" THEN GOTO 2 ELSE Num% = 10 * VAL(k$)
4 k$ = INPUT$(1)
5 IF k$ < "0" OR k$ > "9" THEN GOTO 4 ELSE Num% = Num% + VAL(k$)

With local echo:

Code:

1 PRINT "Enter a two digit number: ";
2 k$ = INPUT$(1)
3 IF k$ < "0" OR k$ > "9" THEN GOTO 2 ELSE Num% = 10 * VAL(k$): PRINT k$;
4 k$ = INPUT$(1)
5 IF k$ < "0" OR k$ > "9" THEN GOTO 4 ELSE Num% = Num% + VAL(k$): PRINT k$

*peace*

Trust Meg to come up with a nice clean approach.
Nice work, Meg.
Better late than never. :wink:
