`GR4_RGIVE(NX,NY,CONV,R)`

This subroutine passes a two-Dimensional array to GREG as the Regular Grid array used for mapping.

NX,NY Integers, array dimensions CONV Real(KIND=8) array of dimension 6 It contains respectively CONV(1) Reference pixel in X (First dimension of R) CONV(2) X User coordinate value at CONV(1) CONV(3) X User coordinate increment per pixel (may be negative) CONV(4)-CONV(6) same as above for Y (Second dimension of R) R REAL array (NX,NY) to be transferred.If R is Real(KIND=4), the array is not physically copied but its address is computed by GREG for later use. GREG will not modify anything in it. If of type Real(KIND=8), virtual memory is allocated to create a Real(KIND=4) array of same dimensions.
