Neil suggested using LOCATE rather than INDEX in my example. I'm not sure I agree that would be any less complex as far as the code is concerned. INDEX and LOCATE are both 'complex' compared with the IF statement, and since LOCATE needs its SETTING variable, it's arguably the more complex statement. There are three different forms of LOCATE, so that can cause problems. Lastly, the variable TEST has to be set up with attribute marks either by multiple lines or by the very long line below; which, I have to say, I don't find very readable at all.
TEST = 'AF1':@AM:'CK1':@AM:'CK2':@AM:'GS1':@AM:'H':@AM:'JM':@AM:'LHC':@AM:'MP': @AM:'MP3':@AM:'NU1':@AM:'NU2':@AM:'TK1':@AM:'TK2' There may be a slight speed benefit in restricting the scan by using 'AL'; but this is not material (or possibly even detectable?) in strings of this length. There is also an ongoing maintenance risk because the next programmer might not notice the codes were sorted, and may just add a new one to the end of the string.
