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
