How can I find special characters in a string

Hi kwan,

you can use the "search and replace" function, "match pattern" or you convert your string to an array of U8 and use some Array functions to do it.

I recommend to see also this link.

Hi Kwan,

       U could use "Scan from String" function to find any character match

Hi..

   This may help.......

What is your definition of a "special character", could you be a bit more specific?

Do you simply want to find the position of a specific character in the string?

Can it occur more than once and you want to find all occurences?

What should happen if the special character does not exist?

For programming purposes, all 256 possible 8 bit characters (x00-xFF) can be treated the same. Non-printing characters can be entered in \-codes or hex display if needed.

I'm trying to search within a *.txt file and i'm looking for the $ character.

The *.txt contains thinks like these:

datadatadata$variable

I'm trying to extract the name of the variable. Can any one help?

There are about 10 variables per text file and the variable name may be different between files.

Thanks!

I found the solution I must add the "\" character to match special characters! Thanks!
