System Data Item Descriptions
GLB.BASE
GLB.CCS
GLB.BASE is a read-only System data item which holds the value of the year upon which
relative day numbers are based. Its value is used by the complex form of the
DATE.CONVERT; command.
The value of GLB.BASE is set on the Specification Options screen, using the Base year
field. You can set this field to any year in the range 0001 through 9999. The default value is
1957.
LENGTH = 4 EDIT = N
Note: This System Data item is valid for an OS 2200 based LINC System only.
GLB.CCS is a read-only System Data item that stores the Coded Character Set (CCS)
identifier (CCS ID) for input messages from LT300 terminals. It can be accessed in Ispecs
and Reports.
For example, when using the GLB.CCS in your LINC logic:
$ You can define a data item in your LINC database to contain the CCS of the data. Then,
on input, move GLB.CCS to your data item to indicate the CCS of the data input from
the LT300 terminal.
$ When processing a record in your database, you can use the CCS when making data
comparisons to distinguish names in different character sets. You could use the CCS as
an Ordinate of a Profile, so that you can access names in name order within a
character set.
$ When outputting to the screen, you can compare the CCS stored in the database with
GLB.CCS. If the values do not match, a message can be output to advise that the data is
in a character set that cannot be displayed on the screen.
For details about the available character sets and their CCS IDs, see the OS 1100 EXEC
System Software Executive Requests Programming Reference Manual and the Message
Control Bank (MCB) Programming Reference Manual. For guidelines on
internationalizing applications for an OS 2200 environment, see the Internationalization
(I18N) Planning and Implementation Overview.
GLB.CENTURY
LENGTH = 5 EDIT = N
Use GLB.CENTURY in conjunction with the DATE.CONVERT; command. If your input to
the DATE.CONVERT; command does not contain the century, you should move the
century into GLB.CENTURY.
