AST_CLEAR

Clear attribute values for an Object

Description:

This routine clears the values of a specified set of attributes for an Object. Clearing an attribute cancels any value that has previously been explicitly set for it, so that the standard default attribute value will subsequently be used instead. This also causes the AST_TEST function to return the value .FALSE. for the attribute, indicating that no value has been set.

Invocation

CALL AST_CLEAR( THIS, ATTRIB, STATUS )

Arguments

THIS = INTEGER (Given)
Pointer to the Object.
ATTRIB = CHARACTER ( ) (Given)
A character string containing a comma-separated list of the names of the attributes to be cleared.
STATUS = INTEGER (Given and Returned)
The global status.

Applicability

Object
This routine applies to all Objects.
