Problems using %ismember
|
Hi there,
Basically I'm trying to use #IF and %ismember to determine whether any of the values stored within a string list occur on another string list, then have a particular event occur if they don't.
I've tried the following...
#if (%ismember(@variableA,@variableB)) {} {result}
... but with little success.
I've tried to avoid using "#FO @variableA", on the grounds that I want the result to occur only if -none- of the values of variableA are on variableB, not for every single one that isn't.
Any advice on this would be appreciated. |

#variable member_count 0
#forall @list_a {#if %ismember(%i,@list_b) {#add member_count 1}}
#if (@member_count = 0) {#echo no common members} |
