Re: FTP and CRLF

A couple of ideas:

 - Try record structure mode by using the subcommand STRUCT R (if
scripting from the PC, you may need to use QUOTE STRUCT R if the PC
client does not recognize the STRUCT command).  This will retain the
record sturcture (including trailing blanks) and delimit the records
by a x'FF01' instead of a CR/LF.  If your PC software doesn't hiccup
on the x'FF01', you just need to put this in your script prior to the
GET or PUT subcommands.

 - Pass the PC file with the CR/LF through a filter to strip out the
CR/LF sequence after the FTP completes.  The PC program to do this
would be trivial using something like AWK or Perl.  In fact, here is
the source to do it in AWK:

{ printf( "%s",$0 ) }

This sets up an automatic loop to read each "line" of text into
variable $0, then perform a formatted print where the format is a
simple string.  Using a formatted print suppresses the addition of a
CR/LF on output, so the net effect is repeating the input but without
the CR/LF.  In a batch file, you'd use this with redirection of stdout
so the "print" was to another file.  (EG,  "StripCRLF input.txt >
output.txt")

I can compile the source above and send it to you as either a DOS
executable or Win32 executable.  One caveat: the source above will
retain trailing blanks if they existed, but your input file would need
to have fixed length records or your output would be garbage.  I can
pad or truncate lines to a predetermined standard width if you want
just by adding the size to the format string above.  Or I can accept a
command line argument to set a fixed width for the output.  But then
it is no longer a 1-lliner. 

If STRUCTure Record doesn't do it for you, and nobody else has a
better suggestion, tell me if you need the output width adjusted or
just a simple strip of the CRLF, and I'll send you a program to do it.
