Being native's the reason I thought of using trim too - and with good reason, it seems... The script... ----------------- rebol [] print "remove-each..." start: now/time/precise loop 1'000'000 [remove-each val "1234a5b6v77" [any [val < #"0" val > #"9"]]] print now/time/precise - start print "trim/with..." chrs: "" repeat n 256 [append chrs to-char n - 1] chrs: exclude chrs "1234567890" start: now/time/precise loop 1'000'000 [trim/with "1234a5b6v77" chrs] print now/time/precise - start ----------------- And the results... >> do %/c/program%20files/rebol/view/test.r Script: "Untitled" (none) remove-each... 0:00:07.313 trim/with... 0:00:02.343 Now if onlt trim worked as expected! (Someone else can add the parse test... And Kai, like to give us some real-world results?) -- Carl Read. -- To unsubscribe from the list, just send an email to lists at rebol.com with unsubscribe as the subject.
