METMAP stores a 2 dimensional filled-area map to the Longlib Metafile. Actual output is device dependent. (See also the RAMMAP and TEKMAP routines.) Note, although corners may be rotated, displayed map will be parallel to output device coordinate system. Maximum number of elements in a is (1280x1024).
CALL METMAP(a,dx,dy,nx,ny,x0,y0,x1,y1)
a (I): index array a(dx,dy) for area color/pattern
(device dependent)
dx,dy (I): dimension of a array
nx,ny (I): portion of a array to display
x0,y0 (I): location of lower-left corner of map
x1,y1 (R): location of upper-right corner of map
