Sorry to bother everyone again. I am just beginning my enduring journey of
learning IDL and keep running into obstacles.
My current problem is with printf. I am trying to create a text output
file that can be imported into a spreadsheet. My problem is that printf is
automatically line wrapping. For example:
printf, filetpr, val1, val2, val3, val4, val5, val6,
is producing output where val1, val2, val3, and val4 are on a single line.
But, val5 and val6 are placed on the following line. NOTE: I am actually
trying to print 10 different floats on the same line.
I did think about converting all the values into one long string and
printing that string. But, this issue was still a problem.
Anyone have any ideas about how to fix this? Is a solution even possible?
Thanks,
Alan

Yeah, you and me, both. :-)

When you open the file for writing, set the WIDTH keyword to
as wide a line as you need. 80 columns is the default
for historical reasons. (Are you old enough to remember
punch cards?)
Cheers,
