Parameter Declarations Files for Guardian
Procedures
HP provides a set of declarations, consisting mainly of named constants (literals) and
structure definitions, that can be used for parameters to Guardian procedures. Data
Definition Language (DDL) is used to generate files containing the parameter
declarations for TAL, COBOL, Pascal, and C.
These files are located on the subvolume $SYSTEM.ZSYSDEFS. The files ZSYSTAL,
ZSYSCOB, ZSYSPAS, and ZSYSC contain declarations for TAL, COBOL, Pascal, and
C, respectively. The DDL declarations that are used to generate the ZSYS files are in
the file ZSYSDDL.
Your application should include the appropriate compiler instruction specifying the
name of the parameter declarations file you want to use in your application. Refer to
your programming language reference manual for information about compiler
instructions.
For example, to use the TAL parameter declarations in a TAL program, you would
include a SOURCE compiler command specifying the file
$SYSTEM.ZSYSDEFS.ZSYSTAL. The SOURCE command should follow the global
declarations and precede the first use of an item from ZSYSTAL in your source
program. Refer to the TAL Reference Manual for details on using the SOURCE
command in a TAL program.
