GDDL contains DDL source code that can be run through the DDL compiler to
produce UOW definitions for programs written in FORTRAN and TAL. (You can
also use this file to produce UOW definitions for SCREEN COBOL and COBOL
programs, although the GCOB and GLNK files generally serve that purpose
better.)
Note Although Tandem provides files containing UOW definitions for programs written in SCREEN COBOL,
COBOL, TAL, and FORTRAN, you must write your own definitions for programs written in Pascal and C.
Remember this constraint when selecting the language for coding your application programs.
You can copy the code from GCOB or GLNK into a SCREEN COBOL or COBOL
source program by coding the record level and then using the COPY statement.
COPY copy-text OF " filename "
copy-text
is the unique name for the definition in the named file. You determine the correct
copy-text name by searching the files.
The format of the UOW definitions in the GCOB, GLNK, and GDDL files and the
format of those definitions as described in this manual differ slightly from one
another. The following list summarizes these differences:
The manual documents all commonly used definitions in fully expanded form,
while the GDDL file uses the DDL shorthand notation TYPE * to refer to a
definition that has been previously defined. For example, the manual defines the
ITEM-ID field as:
02 item-id.
03 dummy PIC X(12).
The GDDL file, however, defines ITEM-ID once as an individual definition, and
shows this field on subsequent references in the form:
02 item-id type *.
