      I would like to use regexp to search a string in a free text comment field for the entires tba or TBA or aop or AOP. These entries can be entered with a / or – or blank space preceding them. I have tried the example regexp {^(tba|TBA|aop|AOP)$} $comment but I am unsure how to extract if it is there inside of a tcl script. I want to know if it is there and place that entry into another field for one of our downstream systems. Any help would be gratly appreciated. Thanks

          It should be as simple as adding a variable to the end of your regexp.

          $  set comment “this is an aop type comment”

          $  regexp {(tba|TBA|aop|AOP)} $comment output

          $  1

          $  puts $output

          $  aop

          This is assuming you don’t want the – / or blank space returned.  You may also want to drop the ^ and $ from your regexp unless the string will only contain one of the four values.

          Hope this helps.

            Better still:

            set val “”; regexp -nocase {(TBA|AOP)) $str val

            If either value is there, val is set to the value, else val is the empty string
