 ;                   schedule the task in Taskman
 ;    queue up the first job to ZTIO="" and schedule it
 ;  %RTN - required - [tag]^routine for the 1st job to be run (usually a
 ;                    search and build sorted data type process)
 ; %DESC - optional - ZTDESC value for 1st job (default [tag]~routine)

 ;  %ZIS - optional - see %ZIS description above, except for one diff
 ;         the 2nd job will be tasked to this device call
 ;         exception: IF $D(%ZIS)=0 then default value is "MQ" and call

 ;                    be added
 ;   %WR - optional - see above
 ; %RTN2 - required - [tag]^routine for the 2nd job to be run (usually a
 ;                    print job)
 ;%DESC2 - optional - ZTDESC value for 2nd job (default [tag]~routine)
 ; %VAR2 - optional - ZTSAVE values for 2nd job - see %VAR descript above
 ;         if %VAR1 is not passed and $D(%VAR) then also send %VAR
 ;         data to 2nd tasked job.  If $D(%VAR1) then do not send %VAR

 ;         needed - note: if %VOTH1("ZTDTH") is passed it will be ignored
 ;         as it is necessary to S ZTDTH="@" for the 2nd job - this will
