 Q
 ;
 ;***** CREATES AND SCHEDULES A TASK
 ;
 ; TYPE          Type of the task (1 - Generic, 2 - Report)
 ;
 ; ZTRTN         The entry point TaskMan will DO to start the task.
 ;
 ;               This parameter can also have the $$TAG^ROUTINE
 ;               format. In this case, the "proxy task" will be used.
 ;               The value of the parameter will be saved in the
 ;               RORTSK("EP") node and the "TASK^RORTSK01" will be
 ;               assigned to the ZTRTN variable. See the TASK^RORTSK01
 ;               for more details.
 ;
 ; [.PARAMS]     Reference to a local variable that contains a list
 ;               of name-value pairs of the task parameters.
 ;               The parameters are passed to the task as sub-nodes
 ;               of the "PARAMS" node of the RORTSK local variable.
 ;
 ;               Examples:
 ;
 ;                 PARAMS("NUM")=10    ==> RORTSK("PARAMS","NUM")=10
 ;                 PARAMS("A(10)")="B" ==> RORTSK("PARAMS","A",10)="B"
 ;
 ; [REGIEN]      Registry IEN (if $G(REGIEN)'>0 the task will not
 ;               be associated with any particular registry).
 ;
 ; [REPORT]      Code of the report (if the TYPE = 2).
 ;
 ; [SCHCODE]     Rescheduling code for the task. By default (if
 ;               $G(SCHCODE)=""), the task is executed once. See
 ;               description of the $$SCH^XLFDT function for
 ;               possible values of the parameter).
 ;
 ; [.RORTSKPP]   Reference to a local variable that contains a task
 ;               descriptor with already prepared task parameters
 ;               (under the "PARAMS" subscript). These parameters
 ;               are copied into the new task descriptor "as is".
 ;
 ; All other input variables used by the %ZTLOAD (except the ZTRTN)
 ; can be used to control the task. Modifications of the default
 ; behavior of some of those variables are described below.
 ;
 ; [ZTDESC]      Task description
 ;
 ; [ZTDTH]       Date/time to start the task (FileMan). By default
 ;               (if $G(ZTDTH)=""), the task is scheduled to run
 ;               with a 3 second delay.
 ;
 ; [ZTIO]        Output device. By default (if $G(ZTIO)=""), the
 ;               task is started without an output device.
 ;
 ; [ZTSAVE]      List of variables that should be passed to the task.
 ;               The CREATE^RORTSK function adds the "RORTSK(" item
 ;               to the list if the task proxy is requested (see the
 ;               ZTRTN parameter for details) or the PARAMS parameter
 ;               is defined.
 ;
 ; Return values:
 ;       <0  Error code
 ;       >0  Task Number
 ;
