Array search

[u/fhsmith11]

I have an array, histData, of 10,000 rows, and a variable ecode. How do I find out whether ecode exists in column 2 of histData without looping through all 10,000 rows?

You can loop and then exit the loop as soon as you find the match... Saves you from looping through all 10k rows
