Thanks, I did not notice that. Probably the reason it's not working the way
I thought it was going to.

Looking at some doc on _C_IFS_fgets, it does not sound like a good api
to use when reading an image file. It seems to be intended for text
base file.

Also, you said you used unix's send api, I'm assuming that you are
referring to the socket send() api. This api has 4 parms and one of
them is the buffer/data length. How does your SendtheData() determines
the buffer length?

I do not know how those api work. However, it looks strange for me to
see %trim(BufOut) being used when attempt to use api to send the data.
Use of %trim would alter the data, which breaks the rule of sending the
data as it.
For example, if BufOut contains a string that happen to have leading
blanks, the %trim will strip them out before api sending it.

Using FTP is not an option for this particular application.
Looking at the data a little closer in a tool that compares two
files...if I look at the data from a copy of the image file that I FTP
to the PC and compare it to the one sent over the socket, I can see
where there is a bunch of blank spaces inserted into my file, and it
looks like possibly a carriage return or line feed is being inserted
there too.
It has to be a buffer length issue or something like that.
Here's the relevant bit of code:
The variable bufOut is 32,767 bytes long (character field)
D ifsReadLine PR * ExtProc('_C_IFS_fgets')
D inBuffer * Value Options(*String)
D inBufLen 10i 0 Value
D inFilePtr * Value Options(*String)
*------------------------------------------------------------
C Dow ifsReadLine(%Addr(BufOut):
C %Size(BufOut):zp) <> *NULL
C callp(e) SendtheData(socketDescriptor:
%Trim(BufOut))
C Eval BufOut = *Blanks
C Enddo
