concatenating strings...

[Scott Turchin]

I have a weird issue.
Perhaps it's simply because the TCP/IP Stack is returning $CRLF in my string.
I call for the username (My app is an FTP server, rfc compliant etc)...
g_IncomingUser is then filled with say "tngbbs"

So I say:
buffer = "331 password required for " + g_InComingUser
And this is required otherwise, a $CRLF is appended on g_IncomingUser:

buffer = Remove$(buffer,Chr$(13))
buffer = Remove$(buffer,Chr$(10))
Tcp Print gSock(i),buffer

Am I to assume this is because the FTP client appended it and I have to strip it off? I suspect so...

I haven't used the TCP/IP functions very much, but it seems pretty clear that if you do this...

buffer = "331 password required for " + g_InComingUser

...and you end up with a string that ends in CR/LF, then the g_InComingUser variable (or function) must be the source of the CR/LF. I can't imagine that PB would ever, under any circumstances, add extra characters as part of a string-concatenation operation. Is that what you're asking?

Scott --
Such statements as Tcp Recv #f, kBuffer, Buffer$ brings CR/LF (it's a part of server reply)
But instead of Remove you can simply add semicolon after TCP PRINT

scott,

while not directly related to your problem, you can remove$ more than one character in one go:

<font face="courier new, courier" size="3"><pre>buffer = remove$(buffer,chr$(13, 10))[/CODE]

or

<font face="courier new, courier" size="3"><pre>buffer = remove$(buffer,$crlf)[/CODE]

will both do the same job as your two lines. not really important in this context, but if you're removing a lot of characters it's a lot easier. finally, using

<font face="courier new, courier" size="3"><pre>buffer = remove$(buffer, any $cr & $lf)[/CODE]

will remove any cr and lf characters, whether they're together as a pair or by themselves.

the equates i've used are built-in but "undocumented" - they're not part of the docs, but listed in the faq forum ( http://www.powerbasic.com/support/pb...hread.php?t=34 ).
