Here is my current setup for a parameter:

select {?Client}

case "XNORT01" : "North Lambeth"
case "RLBLH05" : "Hostels"
case "RLBLE01" : "Ethelred"
case "RLETT01" : "Lettings First"
case "RHOLL01" : "Holland Town"
case "RCEDA01" : "Cedars"
case "RCROY01" : "CCHA"
case "RSOUT01" : "Southern"
case "RGALL05" : "Gallions"
case "RPENG01" : "Penge"
case "RSWAN02" : "Swan"
case "RPEAB01" : "Peabody"

// FY 07-08 Client Codes

case "RCROY03" : "CCHA"
case "RPENG03" : "Penge"
case "RSWAN03" : "Swan"
case "RHOST04" : "Hostels"
case "RCEDA02" : "Cedars"
case "RETHE02" : "Ethelred"
case "RHOLL03" : "Holland Town"
case "RLETT02" : "Lettings First"
case "RNORT04" : "North Lambeth"
case "RSOUT10" : "Amicus Horizon Croydon"
case "RWAND01" : "Wandle"
case "YSLFH01" : "SLFHA"
case "YSWAL01" : "Swale"
case "YEAST*" : "East Thames"

All I need to do is edit this script to allow for multiple selections. Is it possible? With the CASE syntax, can I add * in the quotes as if using LIKE or can I do an IN selection ["xyz", "abc"] before the colon? Or do I have to do another CASE line with various contents before the colon, and the same contents after it?

eg.
case "XNORT01" : "North Lambeth"
case "XNORT02" : "North Lambeth"


I want to put all sorts in there which OR into the outcome on the right. These reports have been done better without CASE. Easier to modify this one as it stands

or do I have to write all this without the CASE? I'm happy to if necessary for multiple selections.

Thanks

select {?Client}
    Case "XNORT01" ,"XNORT02":
        "North Lambeth"
    Default:
        "Others"

I hope this helps you!
