Setting Dynamic Defaults
The ADAM parameter system has the concept of `dynamic defaults' for program
parameters. These are values suggested by the program itself and the
Interface Module
may be set up to cause the dynamic default to be used as the value for a
parameter using the
VPATH Field (see SUN/115),
or given as a suggested value in a prompt, using the
PPATH Field (see SUN/115).
Subroutine
DAT_DEF
can be used to set an HDS object as the dynamic default for a parameter but its
usefulness is limited because it has to be given a locator to the object.
The locator need only be valid when DAT_DEF is called, the object
name is found then and stored as a character string.
The string is used when the dynamic default is required.
