Re: Variable length/precision formats?

It is variable, it is a format, and it is an expression. It

to be specified as a variable. What else do you want?

He wants the wierd, indirect, on-the-fly modification of the
format *while* the I/O list it controls is still being processed.
Mystification of the reader seems to be his real intent.

Next he'll want to be able to change the unit number on the
fly:

Read(N, fmt) x, y, z, N, some, more, stuff

Will this really read the last three elements from a different
file than the first three? Which file will it read N from? (Ok,
that has to be the first of the two files, or it can't be made to
work at all. :-) He'd probably like it even better if he could
write:

Read(N, fmt) x, y, z, M, some, more, stuff

Where M was a pointer that was associated with N in some
backhanded and concealed way. The more mystery interactions
the better, apparently.
