;The macro used to build the command descriptor block is (cmddb.) And has the
;Following format (type,flags,data,help,default,additional command data block),
;The type field will contain the command function code, the function codes are:
;
; .Cmkey= 0 ;keyword .Cmusr= 12 ;user name
; .Cmnum= 1 ;number .Cmcma= 13 ;comma
; .Cmnoi= 2 ;guide (noise) word .Cmini= 14 ;init line

; .Cmcfm= 10 ;confirm .Cmnux= 24 ;number delimited
; .Cmdir= 11 ;directory name ; by non-digit
;
;The flag field will contain one of the following flags or will be represented
;By two commas (,,), this indicates to the macro that this field is blank.
;The flags are:
; Cm%hpp ;help pointer is present
; Cm%dpp ;default pointer is present
; Cm%sdh ;suppress default help message
;
;The data field is dependent on the command function, see tops20 monitor call
;Manual commd jsys v544. This field may be omitted by using two commas (,,).
;
;The help field points to a message to be printed if the question mark (?)
;Is typed. This field may be omitted by using two commas (,,).
;
;The default field is pointer to a string to be used if the escape is the first
;Character to be typed. This field may be omitted by using two commas (,,).
;
;The alternate command block is a pointer to a command block to be parsed if
;The parse failed in the first command block. This field may be omited.
;
;The function field is always used but not all other fields are necessarily
;Used. If a field to the right is to be used, the unused fields separating
;The fields must be represented by two commas (,,).
