Re: Problem with FTP_GET, FTP_BINARY when downloading mixed file types

[Scott Klement <sk@xxxxxxxxxxxxxxxx>]

Hi Pieter,

I'm doing a similar type of program with FTPAPI to get PTFs from IBM.  I 
ask for a list of files in the directory, and the ones that end in .txt 
are downloaded in ASCII mode, the the others (which are CD images) are 
downloaded in binary mode.

Works without a problem for me.

In order to take this any further, I need to reproduce the problem. 
Please send me a complete, working program that reproduces the problem. 
  This should be a program that I can load/run on my system, so I can 
see the actual problem and debug the code.

Thanks
