What data are you looking to extract? You need to help us here if you want help.

What do you need to do?

Will the string that you are getting always look like the one that you have provided?

How are you going to get the data?

What have you already tried?

Match Pattern and Scan From String will be your friends here.

Here is what I would do to start:

This will accommodate the multi string that you want to process. You just need to get them into an array to pass to the for loop.

I think it really still depends on what the actual rules for the input string are.

I thought this:

Replacing the input string with an array and a for loop would work.  Or concatenating all strings together would work.

Or you can use a regular expression.

wow..thanks it works .And can i use while loop in visa read for continuous reading a data?i used concanate string to send all the string.But Some string contains only the commands to be set and rest of them contains commands to get.e.g.in my above string C01 is for Get and C04 is for set.How can i read data continuously.i just use visa read and write with out any loop.(see attachment)
