That's why it's a good idea for FORTRAN programmers to include the line IMPLICIT LOGICAL (A-Z) or IMPLICIT CHARACTER (A-Z) in each main program and subprogram. Even better, many compilers now make an IMPLICIT NONE available. I realize that the thought of being forced to declare one's variables is odious to most "traditional" FORTRAN programmers. I still remember students from my T.A. days who would look at me as though I were off my rocker for telling them to use IMPLICIT LOGICAL and declare all their variables. These kids' major, unsolvable problems always seemed to stem from some overlooked misspelling. Of course, in the professional world, such things never happen. ;-) -- Carol Springs "Programmers are allowed five extra years."
