      I am having issues with what I though would be something simple. I need to pull out the first character of a code in the OBR4 field.

      The value is L100.0050, L400.0625 and others.

      When I try to pull the first letter only wanting the “L” but I am getting everything up to the decimal point. So I am getting L100 , L400 .

      Below is my code. Any ideas?

      lassign $xlateInVals begChar

      set NewBegChar [string range $begChar 0 0]

      lappend xlateOutVals $NewBegChar

      is this wrong?

      thanks.

          Kevin,

          Should xlateOutVals only be the first character, or are you truly trying to append the 1st character to the existing value?  If you only want the first character, then I think you need to:

          set xlateOutVals

            I believe xlateOutVals is normally already populated with xlateInVals, and lappend’ing to it would add the additional output value to xlateOutVals (assuming there is another output field listed to house it).  This is probably why you are still seeing the L100 (is the output field only 4 characters in length?)

            You should echo out xlateOutVals prior to executing your code to see what is there.

            that loud thud you heard was my head hitting the desk. knew it was something simple.

            That worked great and makes sense.

            Thanks a bunch.
