Section 1
LINC Logic Commands
Overview
This section covers LINC Logic commands, which define and implement the business rules
of a LINC System in high level logic. Logic commands are entered by using the LINC Editor
for Ispecs, Reports, and Global Logics.
The following general statements apply throughout this section:
$ Commands are listed alphabetically.
$ Commands can be assumed as valid for Ispecs and Reports, and for Global Logic used
in Ispecs or Reports, unless explicitly stated otherwise. Commands available in
Insertable Global Logics depend on where the Global Logics are inserted (Ispecs or
Reports).
Note: Report-only commands will appear as errors in your Insertable
Global Logic but may generate correctly in a Report.
$ Commands can be assumed as valid for all types of target host (UNIX, MCP and
OS 2200 environments), unless explicitly stated otherwise.
$ Further restrictions may be contained in the command descriptions.
$ The syntax of each command is given.
To explain complex syntax, railroad diagrams are used. See Appendix B for guidance
on interpreting these.
Where explanations of command parameters are not included with the syntax
diagram, see ‘‘Conventions for Syntax Diagrams’’, later in this section.
$ The GLB.STATUS; command can be used with many commands to direct the error
status to a specified data item instead of the System Data item GLB.STATUS.
References to the System Data item GLB.STATUS may be taken to mean that specified
data item where appropriate.
Note: The GLB.STATUS; command is not included in the syntax diagrams
of individual commands.
$ In Reports, you can define data items with the same name in several Frames. Use OF;
frame to identify which of these data items is being referenced. If not used, the current
Frame is assumed.
OF; is not a logic command or a command option. It is a data item qualification used to
qualify a Frame data item in a Report logic command. For more details, see your LINC
Generate Operations Guide.
