You could even try
LOOP
READNEXT ID ELSE EXIT
[Code goes here]
REPEAT
This works just fine.

: This format of the READNEXT statement is used in a couple of places in the

:
: If I look up READNEXT in the manual (or in HELP from TCL) - there is no
: mention of this format of the statement.
:
: And in the manual the THEN and ELSE are enclosed in braces: {THEN
statements
: [ELSE statements] | ELSE statements}
: which according to convention means that I have to choose one
"non-optional"
: item.
:
: Has this format of the statement just been left out of the manual by
mistake
: or is it a "new" format, that was never documented.
:
: And, what are people's thoughts on using this format. Personally I dislike
: it, as it isn't easily readable, it's not documented and it's not a
standard
: use of the statement syntax.
