GRAPPAC: A Package of FORTRAN Subroutines for Use with the 6000 Series 274 Interactive Graphics System of the Control Data Corporation,
Abstract
GRAPPAC, a package of FORTRAN subroutines facilitating use of the 6000 series 274 Interactive Graphics System of the Control Data Corporation, is described and programming examples are given. GRAPPAC manages an output buffer for Interactive Graphics System display creation. It also keeps a record of the displays created, in logical groupings of arbitrary size determined by the programmer; the programmer can later call for erasure of any group. Calling sequences are short and simple. Coordinate transformations are automatic. There are linear and logarithmic axis routines and grid line generators. Alphanumeric input from the console is facilitated, with format errors made non-fatal. Error tracebacks are provided. In addition, low level CALCOMP plotting routines have been simulated so that higher level CALCOMP routines can be used within the Interactive Graphics System framework. (Author)
