How to loop strings?

[opto]

I have been trying to use Labview to loop strings but is unable to... is there a way for this to be done?

Hello opto,

what do you mean by "loop strings"?
Do you want to get one char after the other from a string? Then there is a function "string subset" in the string functions palette.
Or do you have an array of strings? Then have a look at the array functions palette or use the auto-indexing feature of for/while loops...

Best regards,

Hi,

I mean when i use match pattern in the string function, after i input the string to match pattern, using shift register to obtain the after substring, i am unable to loop it back to the original string function...:(

Your description does not make much sense, so it is possible that I misunderstand.

Remember, a diagram is worth 1000 words so please attach a small sample VI demonstrating the problem or a image of your code. 🙂

Anyway, matching patterns does not involve any shift registers to obtain the "after substring".
If you need the original string, just branch it off before it enters the match pattern function.

Hello opto,

do you mean something like the attached picture?
This way you "loop" the "after substring" back to your match pattern.

Anyway, like altenbach said: try to post a vi describing your problem!

Best regrards,

thank you. ive solved the problem using the shift registers.
