      Some of our rooms lead with alpha characters.  What is the simplest way to check for alpha and if yes trim it off?  Example – in a translate i can do an   If 0(0).PV1(0).#3(0).[1]  ct =A  do Y action, but how would i check to see if it contains any value from [A-Z]?  Then if does, then do something?  Like get rid of the alpha character?

          You will need some Tcl.

          string trimleft $var {[A-Z]} should work if the first character is always upper case.

          If it is mixed case you may need to do a case change on the value (in this example the value from XlateInVals is placed in a variable named var – use your own variable name if you like).

          Remember the Xlate In and Out variables are Tcl Lists and need to be treated as such.

            set var [lindex $xlateInVals 0]

            regsub -all -nocase — {D} $var {} var

            set xlateOutVals

              The above will get rid of anything in the string that is not a number

              It looks like string trimleft $var {[A-Z][a-z]} might take care of upper and lower case (if you just want to trim off of the left side.

                Awesome thanks for the reply.  This works.  I guess I was asking if, within the translate, for an IF statement condition, can you check a range of values versus doing something like the below or a preproc:

                0(0).PV1(0).#3(0).[1]  ct =A ||  

                0(0).PV1(0).#3(0).[1]  ct =B ||  

                0(0).PV1(0).#3(0).[1]  ct =C ||  

                0(0).PV1(0).#3(0).[1]  ct =D

                then do something like

                copy 0(0).PV1(0).#3(0).[1] to 0(0).PV1(0).#3(0).[1] using preproc

                set xlateOutVals

                  1 end ]]

                  Or

                  a trimleft like

                  set ex [lindex $xlateInVals 0]

                  set ex [string trimleft $ex Z]

                  set xlateOutVals

                    Or use your examples

                    My question surrounds only the IF portion and the condition statement in the GUI.  Can you check for a range within the IF condition?  Like a ct =[A-Z]?  (something like that to show intent).

                    FYI I ended up using a combination of both of your example for different things.  Thank you.

                    As far as I know as of this time the IF Action does not support range checking as you describe. Tcl is there to provide such extension.

                    Glad to hear you have it solved.
