Determine a single character's indexes on a string

[Forsaken Angel]

Hello

I am develloping a program in which I need to determine the index (position) of every 7D character on a hexadecimal string. The result should be stored in an array with the position of every 7D character.

I used and tried the code in attachment but it did not work. Can you help me with this? Thanks in advance

here's a VI that should get you started.

I couldn't open the file. I forgot to mention that I am using Labview 7.0 Express, my bad. Could you post it again?

Thanks for the help, I do appreciate it.

Try this...

As to the original code: Your problem was that you should have a shift register for your array. Otherwise, you're just spitting out the last iteration's value.

A far easier solution is to convert the string to a byte array and to do the following (I think it should be obvious what's in the False case):

Thanks, it worked. Looks like it was simpler than what I thought. I guess I was not thinking in the right way.

For fun, here are two more possibilities using "search string" and "search array", resp.

(Note that real LabVIEW programmers start counting at zero, so the first position is position zero, etc. :))
