sending string and decoding

hi everyone,

I am sending serial data to PIC via rs232 port using Visual Basic.
The data is like this "f123k456h789".

I get these data to 18f452 by using gets().

How can I separate this data to:

f,123k,456,h,789

Then I am going to use it in PIC code.

thanks

Thanks for help. However it is not the answer I want I think. I need to find a command or something like that is used for splitting the string and get the characters that I want.

Sorry. I put in the wrong link. I have corrected it now.

Just out of curiosity, why don't you send the data with the ',' commas in the string?

At that point, loop through all chrs, building a new string, and when you encounter "," process what you have thus far, then continue.

Or do you have a string when each field is separated by ',' and thus not data items? ie: 'username,phone,cell_phone' type of thing?

If the latter is the case, I usually make an array of strings, and parse the string into the array, such as GPS data, then I know which field has the data I want.
