pushma(3G)

NAME
     pushma - pushes down the transformation matrix stack

FORTRAN 77 SPECIFICATION
     subroutine pushma

PARAMETERS
     none

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

     pushma operates on the single transformation stack when mmode is MSINGL,
     and on the ModelView matrix stack when mmode is MVIEWI.  It should not be
     called when mmode is MPROJE or MTEXTU.
