how to change a value in a string

[vtince]

I have labview read data from a radio and it sends out a test string in hex of <5050 5058 5858 5858 5858>, I want to be able to change the 4th bit to <50>, and keep all the other values the same as it was read from the radio.

String subset to get the first 3 bytes, and to get bytes 5 and beyond. Then string concatenate to combine the first 3, with a constant of 50, and the 5th byte through the rest.
