How does the "VAL" statement work in Micromite Basic?
I get ZERO value.


Text$="Test"
for i = 1 to LEN(Text$)
DA$ = MID$(Text$,i,1)
DT1 = VAL(DA$)
Print "Text$="Text$" DA$="DA$" DT1="DT1
next i


>
> run
Text$=Test DA$=T DT1= 0
Text$=Test DA$=e DT1= 0
Text$=Test DA$=s DT1= 0
Text$=Test DA$=t DT1= 0

Val converts a string into its equivalent numeric value.
Letters of the Alphabet are not Numeric so return 0.

Change your test string to Text$="1234"
and run it again you will see what I mean.

Just try

Print val("5")

or
a$="123"
Print val(a$)

or use ASC(arg) to returns the ASCII code for the first letter in the argument

Thanks for quick reply.
Is there a way to get the ascii value of a text character?

Maybe you are looking for ASC?
The Ascii value of a character?

Thanks. Yes, that's what I need. The ascii value of text character. The "VAL" statement confused me thinking it would give me the ascii value.

I used VAL all the time by mistake when I needed ASC, if that makes you feel any better. It would seem to be a common mistake when learning.
