System Data Item Descriptions
The value of GLB.TASK is stored in T3 of the Run Condition Word and can be tested later
in the same runstream by a succeeding task.
Note: LINC Reports generated as LINC Subroutines cannot use this System Data
item.
If you use a MOVE; command to move a value to GLB.TASK, T3 of the Run Condition Word
is set immediately. If you use any other command that has GLB.TASK as a receiving field,
GLB.TASK is set only at the end of the Report.
If the LINC Report terminates normally, the error status of the current task is cleared and
the value in GLB.TASK is stored in T3 of the Run Condition Word. If the LINC Report
terminates abnormally, the error status of the current task remains as it was set in T3 of
the Run Condition Word.
GLB.TASK is zero unless it is explicitly given a value.
For more information on Run Condition Words, see your OS 2200 Based LINC
Administration and Operations Guide.

For UNIX
For Reports initiated using the runrep shell script, you can determine the value of
GLB.TASK from the return code of a LINC Report, and use that information to control
dependent actions. The Report will return a value of zero through 99 to indicate the Report
has successfully completed, or 100 through 199 to indicate that it has failed.
You should set the value of GLB.TASK to a number in the range 60 through 99. This is
because UNIX returns values in the ranges 1 through 31 and 129 through 159 if a Report is
terminated by using a UNIX kill or a :TER LINC System command.
For a description of the use of GLB.TASK for UNIX LINC System Reports, see your UNIX
LINC Administration and Operations Guide.
GLB.TASK defaults to zero.
LENGTH = 2 EDIT = N
For LDA
Moving a value to GLB.TASK causes the task value to be set. This value can then be tested
by the program initiator. This value is written to ERRLOG.TXT at the completion of a
report or at the end of an online session. This value is also written to the log file if logging
is enabled.
The initial value of GLB.TASK is zero.
