This is the TPU Code associated with the selected label.

  You can can edit this field, and then press the Triangle in the lower
  right to modify a label.

  Portable LSE commands can be translated to TPU code as follows:

                o  Replace all spaces between command reserved word with a
                   "_"

                o  Add a "LSE_" to the front

                o  Enclose individual parameters in '"'s

                o  Enclose all the parameters in "()"

  For example:

                o  OPEN FILE foo.bar becomes LSE_OPEN( "foo.bar" )

                o  SHOW SUMMARY becomes LSE_SHOW_SUMMARY

                o  "SET DIRECTORY READONLY foo off" becomes LSE_SET_
                   DIRECTORY_READONLY( "foo", "off" )

  On OpenVMS systems, VMSLSE commands may also be used within menu
  label definitions by calling the LSE$DO_ COMMAND procedure, with the
  VMSLSE command enclosed within quotes.
