Bug PERL: How do i print an associative matrix?
Hello guys,

I have in PERL an associative 2-dimensional array, called matrix. The array (actually the matrix) is made up like this
Code:
matrix[a][c] = x;
matrix[a][d] = y;
matrix[b][c] = w;
matrix[b][d] = z;
...

but the names a, b, c, d are set just at runtime.

The question is: how can i get all the keys of the matrix (i.e. a, b, c, d) and print the all matrix?

Thank you very much for your help!

Sergio

glmatrixmode

GLMATRIXMODE(3G)														  GLMATRIXMODE(3G)

NAME

       glMatrixMode - specify which matrix is the current matrix

C SPECIFICATION

       void glMatrixMode( GLenum mode )

PARAMETERS

       mode  Specifies which matrix stack is the target for subsequent matrix operations.  Three values are accepted: GL_MODELVIEW, GL_PROJECTION,
	     and GL_TEXTURE.  The initial value is GL_MODELVIEW.

	     Additionally, if the GL_ARB_imaging extension is supported, GL_COLOR is also accepted.

DESCRIPTION

       glMatrixMode sets the current matrix mode.  mode can assume one of four values:

       GL_MODELVIEW		Applies subsequent matrix operations to the modelview matrix stack.

       GL_PROJECTION		Applies subsequent matrix operations to the projection matrix stack.

       GL_TEXTURE		Applies subsequent matrix operations to the texture matrix stack.

       GL_COLOR 		Applies subsequent matrix operations to the color matrix stack.

       To find out which matrix stack is currently the target of all matrix operations, call glGet with argument GL_MATRIX_MODE. The initial value
       is GL_MODELVIEW.

ERRORS

       GL_INVALID_ENUM is generated if mode is not an accepted value.

       GL_INVALID_OPERATION is generated if glMatrixMode is executed between the execution of glBegin and the corresponding execution of glEnd.

ASSOCIATED GETS

       glGet with argument GL_MATRIX_MODE
