NAME

pushmatrix − pushes down the transformation matrix stack

SPECIFICATION

C
pushmatrix()

FORTRAN
subroutine pushma

Pascal
procedure pushmatrix;

DESCRIPTION

pushmatrix pushes down the transformation matrix stack, duplicating the current matrix.  For example, if the stack contains one matrix, M, after a call to pushmatrix, the matrix contains two copies of M.  The top copy can be modified. 

The transformation matrix stack is eight levels in hardware and is 32 levels in software.
