System Data Item Descriptions
GLB.WORK
GLB.WORK can be used in Ispec logic for transferring information between Ispecs. It is
associated with each terminal user, and is unaffected by the activity of other terminals in
the network.
GLB.WORK is accessible from all Ispecs in the LINC System. Values are usually stored and
retrieved from GLB.WORK by using either complex MOVE; commands or Group Setup
Data items, or automatically by specifying a Global Setup Data item (GSD) or Group GSD
name in the Global Work GSD field on the Primary Specification Options screen. For
more details, see your LINC Generate Operations Guide.
If the specified Global Work GSD contains initial values, these will be overwritten by the
contents of GLB.WORK. Thus initial values used in this context have no effect. The
contents of the Global Work GSD are not cleared by automatic logic, but are overwritten
by the contents of GLB.WORK.
You can preserve the contents of GLB.WORK between sessions by selecting the option
Preserve Session Data on the Primary Specification Options screen. For more details,
see your LINC Generate Operations Guide.
You can also specify the length of GLB.WORK on the Primary Specification Options
screen. The default minimum length is 128 characters. The maximum is 2000 characters.
For LDA Run Time, the length is assumed to be greater than 24.
GLB.WORK is recovered with the LINC System. It is maintained when GLB.ERROR is set
to (*****), but not when Teach screens are displayed. GLB.WORK can be used by GLI
input, although it is not available for Offline input or External Automatic Entries.
GLB.YYMMDD
GLB.ZEROS
LENGTH = 128 to 2000 EDIT = A
This read-only System Data item contains the current date (or the debug date, if debug date
and time is activated) in YYMMDD format; for example, 980323, (for March 23, 1998).
GLB.YYMMDD is accessible in Ispec logic only.
LENGTH = 6 EDIT = N
GLB.ZEROS is a read-only System Data item that can be used in place of a literal value of
zero (for comparing, ordering, and sorting purposes) on any host type.
