AGI_SROOT - Select the root picture for searching

Description:

The root picture is selected for searching operations. The root picture contains all other pictures (including the base picture) and can be used to recall any picture whether it lies within the current picture or not. This is used to override the usual restriction that a recalled picture must lie within the bounds of the current picture. The root picture is automatically deselected after a call to any of the recall routines AGI_RC $*$ . Recall is the only operation allowed with the root picture, any other operation called while the root picture is selected will use the current picture.

Invocation:

CALL AGI_SROOT( STATUS )
