This routine exports an Object pointer from the current AST context into the context that encloses the current one. This means that the pointer will no longer be annulled when the current context is ended (with AST_END), but only when the next outer context (if any) ends.

CALL AST_EXPORT( THIS, STATUS )

THIS = INTEGER (Given)

STATUS = INTEGER (Given and Returned)

Object

• It is only sensible to apply this routine to pointers that have been created within (or exported to) the current context and have not been rendered exempt using AST_EXEMPT. Applying it to an unsuitable Object pointer has no effect.
