This format of the READNEXT statement is used in a couple of places in the
UniVerse BASIC manual. It looks like READNEXT is returning a Boolean.
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.
