22283Re: Finding gaps in a sequence
- Dec 1, 2011Joy,
I also went through your clip again (messages #22230, #22245). I like that formula '^$Calc(^%V1%*676 + ^%V2%*26 + ^%V3%)$' which, actually, seems to be the heart of your solution.
So I combined it with some ideas of my first concept and managed to speed up your clip significantly. Originally, your clip needed 78 seconds (on my notebook) to check a list of 10,000 codes. The following version is doing it in 9 seconds:
; Assign code list to array %List%
; Save current code to variable for later output in case of gap
; Convert code to number(with Joy's formula)
^!If ^%i% > ^%List0% Out
^!IfSame ^%First% ^%Second% CodeToInt Else False
^!IfEmpty ^%Gaps% Next Else Skip_2
^!Info No gaps!
^!Toolbar New Document
^!InsertText Gap found after...^P^%Gaps%
^!Toolbar Second Window
The sublip with custom function ^$Convert$ and your formula is...
^!Result ^$Calc(^%V1%*676 + ^%V2%*26 + ^%V3%)$
Thanks again for your proposal! Maybe you'll have a look at this revised version...
