A simple way would be just to use basic matchText() for each single letter and regex matchText() for repeating letters. P.*P will find double Ps, P.*P.*P will find triple Ps etc. Seems to be relatively fast but if you have very large data sets other alternatives would need to be investigated.
in the message box: put "ABCDEKLP" into X put "ABCDEKLLLLMMOOPP" into Y put 100000 into Z put 0 into a put 0 into b put 0 into c put 0 into d put the millisec into tStart repeat Z times if (matchText(X, "A") AND matchText(X, "E") AND matchText(X, "L") AND matchText(X, "P.*P")) then add 1 to a else add 1 to b end if if (matchText(Y, "A") AND matchText(Y, "E") AND matchText(Y, "L") AND matchText(Y, "P.*P")) then add 1 to c else add 1 to d end if end repeat put the millisec into tEnd put "X Passed " & a & " times." & cr into msg put "X Failed " & b & " times." & cr after msg put "Y Passed " & c & " times." & cr after msg put "Y Failed " & d & " times." & cr after msg put Z & " repeats took " & tEnd - tStart & " ms" after msg The above should take less than 1 sec but for a million repeats I got: X Passed 0 times. X Failed 1000000 times. Y Passed 1000000 times. Y Failed 0 times. 1000000 repeats took 1997 ms NOTE: the above only works if the letters you are looking for can appear in ANY order. If you need a specific order then you'd have to regex matchText() for all searches, ie if (matchText(X, "A.*E.*L.*P") AND matchText(X,"P.*P")) then Yes, the P must appear in both searches to ensure a P has both an L before it and a P after it.
