scalar 'al'='at'[1,1]
scalar 'ak'='at'[1,2]
scalar 'am'='at'[1,3]
scalar 'ae'= 1-'al'-'ak'-'am'
and wonders what might be wrong. These references (and all throughout
the program) must dereference macros with the left tick (accent grave)
on the left, e.g.
scalar `al' = `at'[1,1]
scalar `ak' = `at'[1,2]
scalar `am' = `at'[1,3]
scalar `ae' = 1-`al'-`ak'-`am'
Unless the left ticks have been changed to apostrophes (') by the
email program, they are invalid syntax.
