How to convert characters into numbers?

[venado]

I need to convert characters to numbers. i.e. ASC('A') = 65.
That's fine. How about "AB" or "AC", and so on ...

Does anyone knows about of any vfp capability to do that.

Any help is appreciated.

Thanks,
venado

Venado,
Do you want the numbers in a comma delimited string? In an array? In an integer? (The last would only work for up to 4 characters.)

You'll have to give a bit more information on what you are trying to do before a recommendation can be made.

More info.....

I want the numbers in an integer for further manipulation. The 4 digits will be fine for the purpose of this exercise.

Thanks

If you meant '4 bytes', not 'digits', and you need this to convert binary representation of the number in the string to the numeric variable in VFP (it is used very often when working with API functions), use following:

asc(left(MyString,1)) + asc(substr(MyString,2,1)) * 256 +
asc(substr(MyString,3,1)) * 256*256 + ;
asc(substr(MyString,4,1)) * 256*256*256

Hope this helps.

If you want to play with the numbers after segmenting them out use an array

lcString = "ADFK" or whatever
lnLen = len(lcString)
dimension laArray(lnLen)
for lnX = 1 to lnLen
laArray = asc(substr(lcString , lnX , 1)
endfor
..
code to play with the array
