If the resultant process is DETACHED, the DETACHED process does not have access to the process or job logical name tables of the initiating process. In this case, the resultant job can acquire logical names as follows:
By receiving any assignments made in SYS$LOGIN:LOGIN.COM of the initiating process.
By receiving any assignments made in the file specified by the optional STARTUP parameter.
By processparameters specifying values for I/O and GTM$GBLDIR.
When multiple sources specify GTM$GBLDIR, the last source in the previous list overrides the prior sources. When a JOB is DETACHED, as it is by default, take care to provide the proper environment, particularly logical names for the JOBbed process.
For more information on the GTM$GBLDIR logical name, refer to the "Global Directory Editor" chapter of the GT.M Administration and Operations Guide.
