_GENUUID API Alphanumeric Random String Question

[iseriesmohan]

Hello, I need to a generate a random string of 6 bytes. How can i ensure that the random string i get each time, has never been supplied to my program before ?
I do not see any parameters on the _GENUUID API. Would you recommend anything else ?

A simple solution would be to store each string returned from the API in a physical file. Then check to see if it exists after a call to the API and if found, call the API again...
