# widag(s1, s2, ...) writes the values of the global variables named s1, s2,
# ... with s1, s2, ... as identifying labels.
#
# It writes a diagnostic message to standard error output if an
# argument is not the name of a global variable.
#
# Note that this procedure only works for global variables; there is
# no way it can access the local variables of the procedure from which
# it is called.

write(&errout, image(s__), " is not a variable")
