Modify execution priority of stream task
| Component: | BS2000 |

| Routing code: | J | 
Function
The MODIFY-JOB-STREAM command allows system administrators to change the task scheduling priority defined with the JMU DEFINE-JOB-STREAM statement and to modify stream-specific parameters.
The modifications are valid until the next MODIFY-JOB-STREAM command or until the end of the session.
The default value *UNCHANGED in the corresponding operands means that the previously valid definition still applies.
Format
| MODIFY-JOB-STREAM  | Alias: MDJSR | 
| STREAM-NAME = <name 1..8> ,RUN-PRIORITY = *UNCHANGED / <integer 30..255> ,STREAM-PARAMETER = *UNCHANGED / *NO / <c-string 1..127> | |
Operands
 STREAM-NAME = <name 1..8> 
Name of the job stream whose attributes are to be modified.
 RUN-PRIORITY = *UNCHANGED / <integer 30..255> 
Increases or decreases the program priority of the stream task.
 STREAM-PARAMETER = *UNCHANGED / NO / <c-string 1..127> 
Defines whether stream-specific parameters are to be interpreted.
In addition to the standard scheduler and individual job scheduler can also interpret this operand.
