And no, I'm not referring to my corporeal state as I shuffle along this mortal coil.
I'm referring back to a recent enquiry about sorting an array randomly. There is currently no <@SORT TYPE=RAND...> command so Instead I wrote something like this: <@ASSIGN NAME=temp SCOPE=local VALUE="@@domain$slides"> <@ASSIGN NAME=temp SCOPE=local VALUE="@@domain$slides"> <@FOR STOP='<@CALC EXPR="<@NUMROWS ARRAY=temp SCOPE=local>">'> <@ASSIGN NAME=SLIDENO SCOPE=request VALUE="<@RANDOM LOW=1 HIGH=<@NUMROWS ARRAY=temp SCOPE=local>>"> <@ADDROWS ARRAY=randslides SCOPE=domain VALUE="@@local$temp[@@local$slideno,*]"> <@DELROWS ARRAY=TEMP SCOPE=local POSITION=@@local$slideno NUM=1> </@FOR> You would think this would work but unfortunately when <@NUMROWS ARRAY=temp SCOPE=local> decays to 1 <@RANDOM LOW=1 HIGH=<@NUMROWS ARRAY=temp SCOPE=local>> returns a random between 0 and 32767. So <@RANDOM LOW=1 HIGH=1> is behaving as if no attributes are specified. The klutzy way around this is: <@FOR STOP='<@CALC EXPR="<@NUMROWS ARRAY=temp SCOPE=local>-1">'> <@ASSIGN NAME=SLIDENO SCOPE=request VALUE="<@RANDOM LOW=1 HIGH=<@NUMROWS ARRAY=temp SCOPE=local>>"> <@ADDROWS ARRAY=randslides SCOPE=domain VALUE="@@local$temp[@@local$slideno,*]"> <@DELROWS ARRAY=TEMP SCOPE=local POSITION=@@local$slideno NUM=1> </@FOR> <@ADDROWS ARRAY=randslides SCOPE=domain VALUE="@@local$temp[1,*]"> <@DELROWS ARRAY=TEMP SCOPE=local POSITION=1 NUM=1> I'd personally prefer it if the @RANDOM function decayed as expected and <@RANDOM LOW=1 HIGH=1> = 1.
