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
