Perl- matrix problem

A C G T -
A 5 -4 -4 -4 -5
C -4 5 -4 -4 -5
G -4 -4 5 -4 -5
T -4 -4 -4 5 -5
- -5 -5 -5 -5 0

So lets say I have a matrix which looks something like (above). Its basically a scoring matrix. the numbers are separated by columns are separated by tab and the lines are separated by well a line "\n". So I am trying to write a perl code that reads the file and stores the matrix in anything a list, an array or hash tables... I realize i need to use references but i could be wrong. I was wondering if someone could help me out... I wrote a global alignment program and now i was writing this code so say if i am looking up AA i get 5 if i was looking up TG i get -4
Thanks

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 SEE ALSO
glLoadMatrix, glPushMatrix GLMATRIXMODE(3G)
