SUBTTL Macro to Define the Display Types
;The following macro defines the types of displays which can be output,
;and which have definable columns. (Thus things like the QUEUE display
;won't appear here, since no columns can be changed). The arguments
;are:
;
; XX SEPARATION, TYPE, TEXT
;
;Where separation is the default number of blanks between columns, type
;is the mnemonic for this display used in the column macro later, and
;text is the name of this column for TBLUK purposes. This table must be
;in alphabetical order.

SUBTTL Macro to Define the Columns
;The following macro defines the columns which can be output for a
;fork. The arguments are:
;
; XX ORDER, TYPE, SIZE, ROUTINE, NAME, HEADER
;
;Order gives the default ordering of the columns.
;Type is the type of column this is, without the "TP."
;Size is the number of spaces this column needs in worst case.
;Routine is the dispatch address for this column, without the "XX"
;Name is the keyword name for this column.
;Header is the text output as the header for this column.
