Hello everyone,,,
I have 2 string lists to compare, assume they are as follows:

#VAR colourCheck= {red|black}
#VAR colours= {red|blue|orange|red|orange|green|black|red}

I would like the resulting string list to read:

#VAR colourFound= {red|red|red|black}



Essentially I would like to check the first value in <colourCheck> sequentially against every value in <colours>, then the second value and so on. I am using %additem so i can repeat instances of the same word in the resulting list.

Thanks in advance for the help.

First off i have to comment on the bad syntax of the variable declarations you present (no offense meant, just trying to help.)

Either
#VAR colourCheck {red|black}
or
colourCheck = red|black

On to your question, you want a #FORALL loop, an #IF statement and the %ismember function (use #HELP to read the instructions for either), in addition to the %additem you already mentioned.

colourFound=""
#FORALL @colours {#IF (%ismember(%i @colourCheck)) {#VAR colourFound {%additem(%i, @colourFound)}}}
