Take a look at TESTMGET (rather than TESTGET) Notice the FTP_list() 
subprocedure?  What that returns is a list of files on the FTP server into 
an array in your program.

When you run through the DO loop that follows this function, it's looping 
through the array and calling the FTP_get() procedure for every file in 
that directory (and therefore performing an "MGET" operation)

Since you have the filenames at that point, couldn't you just issue the 
CPYFRMSTMF in the same loop, immediately after the FTP_get()?

I'm assuming (based on the fact that CPYFRMSTMF works) that this is an 
ASCII text file.  Are you using ASCII mode when you download the file?

The other thing I suggested on MIDRANGE-L was that you could use 
FTP_getraw() instead of FTP_get() in order to allow you to use RPG's file 
op codes (such as WRITE, UPDATE, O-specs, etc) to write the results to 
disk. I don't think there are any samples of this in the FTPAPI package, 
but there probably should be.

The specifics of this approach will depend on what type of data is in the 
files you're downloading...
