Subroutine: GGIRCL Purpose: Retrieve descriptive information stored with a Ggi plot device. Category: GRAPHICS File: pgplot.src Author: J.P. Terlouw Use: CALL GGIRCL( CINFO, Output character NC, Output integer RINFO, Output real array NR ) Output integer CINFO - character information to be retrieved NC - number of characters retrieved RINFO - real information to be retrieved NR - number of elements retrieved Description: This subroutine checks whether the device is of type "GGI" and if this is true, it instructs the driver to retrieve the information. Driver function code 23 ('escape') is used for this. If the device is not "GGI", no action is taken. The information must have been stored with a call to GGIRCL, possibly from a different task. The combination GGISTO/GGIRCL can be used to exchange information between tasks which access an exported Ggi plot device. Warning: The sizes of the output variables are not checked. They must be large enough to accommodate the stored information. Updates: Sep 7, 2004: JPT Document created.
