Notes:
VLINE is the original and obsolete name for the linear combination routine VLINCO; it was changed because it clashed with an entry point in some system library.
Usage:
The arguments in the calling sequences below are defined as follows:

found in word G(J,I) of the memory allocated with
DIMENSION G(M,N).
Any summation is taken
over the index I from 1 to N or
over the index J from 1 to M.
