I just wanted to point out that in this context, the Vax Pascal LENGTH function
does NOT return the contents of the varying_string ".length" field.  It returns
the DECLARED SIZE of the particular variable, in this case the value 255, re-
gardless of the number of "valid characters" actually in the string.
