Doug,
Collections all have a “.length”, read only function.
For($i;$Col.length-1;0;-1)
$Col[$i]…
End for
HTH!

*C_COLLECTION*($coll_C)
$coll_C:=*New collection*("Curly";"Moe";"Larry")
*C_TEXT*($name_T)
*For each* ($name_T;$coll_C;0;2)
*ALERT*($name_T)
*End for each*
results in alerts for “Curly”, “Moe”, and “Larry".
*For each* ($name_T;$coll_C;0;2)
*ALERT*($name_T)
*End for each*
results in alerts for “Curly” and “Moe”. That’s expected because the docs
state “end is excluded”.
*For each* ($name_T;$coll_C;2;0)
*ALERT*($name_T)
*End for each*
results in no alerts. That’s not expected.
How does one iterate backwards through a collection? I realize that I can
reverse the collection and iterate forward through it but there’s
no contraindication to iterating backward.
