System Data Item Descriptions
$ An invalid complex MOVE; command is attempted.
$ An Automatic Entry within Ispec logic fails.
$ An External Automatic Entry (between LINC Systems) fails.
$ An External Automatic Entry is rejected by the destination LINC System.
$ An ACCESS.EXTERNAL; command fails (MCP based LINC Systems only).
$ A START; command fails, and the Report is unable to be started.
$ A RUN; command fails, and the Report is unable to be started.
$ A MATCH; command finds both Extract files empty.
$ A WAKE.UP; command with the PARAMETER option cannot pass the parameter to
the Report.
Note: Some LINC commands do not automatically set GLB.STATUS but you are able
to obtain a result in GLB.STATUS by using the GLB.STATUS; command in
conjunction with those commands. The arithmetic commands, ADD;
SUBTRACT; MULTIPLY; and DIVIDE; are of this type. See ‘‘GLB.STATUS (GS)’’
in this manual.
When using arrays, do not use GLB.STATUS for anything other than index
checks. Instead, use the GLB.STATUS extension to the DC; command.
See the relevant commands for more details of the values to which GLB.STATUS may be
set.
When GLB.STATUS is Initialized
GLB.STATUS is set to the value of the System Data item GLB.SPACES before the following
commands are executed:
$ ACCESS.EXTERNAL (MCP based LINC Systems only)
$ AUTO; WRITE, and AUTO; WRITE&CLEAR commands
$ DETERMINE; commands
$ LOOK.UP; commands (except for the LOOK.UP; command variant in Ispec logic)
$ RUN; command
$ START; command
$ MATCH; command
$ WAKE.UP; command
Using the GLB.STATUS; Command
Instead of using the GLB.STATUS System Data item, you can explicitly direct the
command status result to a specific data item, by appending the GLB.STATUS; command
to a logic command, where valid. For more details, see ‘‘GLB.STATUS (GS)’’ in this manual.
