I am more than willing to believe it's a problem with my code. :-) But
I / we need more information before a judgement can be passed. Like,
which architecture is being used, what the input file looks like, etc.
One thing is that TRANSREAD is very line-oriented. It tries to read
one line at a time from the file into a string variable, and then to
parse it. For example, if Dave has a file with thousands of numbers
with no carriage returns, then TRANSREAD will fail because it tries to
read all the data at once. I can't really think of a way around this.
Yours,
Craig

This kind of error often occurs when end-of-line
characters are not in the file. This can occur,
for example, by improper FTP transfer of an ASCII
file from a Mac to a PC. Sometimes popping the file
into a word processor on the target machine and saving
it as a text file will get things sorted out.
This doesn't exhaust the list of possibilities,
of course, but I'm almost certain the problem is not
with Craig's code. :-)
Cheers,
David
