- Subject: I/O operations in binary mode

I am writing a script to parse a binary file and extract some textual
I first used my ProcessFile.lua code template, using readfrom and writeto,
and read"*a". But I quickly found that I had less data that the file has.
I searched the mail archive (I remembered a discussion about binary I/O) and
discovered that the documentation is explicit about the 'b' in openfile
OK, so I am able to do what I want, but I would like to submit a feature
for the sake of symmetry, you should allow readfrom and writeto to accept an
additional parameter, 1 or 'b', to open the file in binary mode. It
shouldn't break compatibility, and it would be nicer...
If this give problems, or if you think this is unneeded / unnecessary /
annoying / ugly / (you name it), you should at least state explicitely in the
manual that these functions can be used only for text files.
While speaking of the manual, there is a small typo in the openfile section:
This string is *exactlty* what is used in the standard C function fopen
BTW, I have put the index of the manual in the manual.html file itself, it
avoids using the back button too often...
