: 
: 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.
: 


Why don't I see this?  I've used this fairly often and it seems I always
came up with the number of valid characters.
