When a job variable is defined as a monitoring job variable, a JV-LINK entry is automatically created with a default link name. Further use of the default link name within the monitored job or the job calling the program overwrites the entry. Access to the monitoring job variable via the default link name is thus lost.
Job monitoring:
A job-monitoring job variable (specified in the command ENTER-JOB, ENTER-
PROCEDURE, PRINT-DOCUMENT, SET-LOGON-PARAMETERS or TRANSFER-FILE) is entered in the JV-LINK table of the job to be monitored with the default link name SMONJVJ during LOGON processing. The monitoring job variable in commands or macros within the job can be referenced by means of this link name.
Use of a temporary job variable is not possible.
Program monitoring:
A program-monitoring job variable is entered in the JV-LINK table of the calling job when a program is started or loaded with the default link name SMONJVP. The monitoring job variable in commands within the job can be referenced with this link name. The program can also access the job variable via the link name. The JV-LINK entry exists from the beginning of monitoring up to the end of the program (TERM or CANCEL-PROGRAM command). Use of a temporary job variable is possible, but other jobs cannot access it.
