Thanks Damien !
>>Unquoted string "justaname" may clash with future reserved word ......"<<
The above seems to imply that it is better to put quotes on file-handles.
Therefore to prevent clashes with future-reserved-keywords, would I be right
to say that it is better to put quotes on filehandles.
Of course I know that to use open-files-handles in UPPERCASE is the best.
Thanks
