L+ L1,L2,K,L
where K is label of an image line of the form "  12.123   12.1   1.123  "
computes the sum of lines L1-L2 for the columns indicated by the numeric
masks on the image line K and writes the sums on the line L acoording to
the same images.
L* L1,L2,K,L
works as L+, but computes products.
L- L1,L2,K,L
computes the difference of lines L1 and L2 to line L.
L/ L1,L2,K,L
computes the ratio of lines L1 and L2 to line L.
L% L1,L2,K,L
computes the ratio of lines L1 and L2 in percentages to line L.
L+log L1,L2,K,L
computes the sums of the logarithms of lines L1-L2.
Other functions available are: sqrt,exp,sin,cos,tan,arctan,int and abs.
The same functions may be included in L-,L*,L/ and L% as well.
