RE: Transfer of File from PC to AS400

Yes, there is a simple way to do it which we are using all the time.

Use the UNIX Api's to write your data directly to the IFS file system. For
example,

  /home/AS400_IFS_Folder/myfile.txt

Then you can use NETSERVER to allow your users to directly access these
files. 

If you have V4R2 or above, you can, also, use the QNTC file system to write
directly to a NT drive on a NT server. For example,

  /QNTC/NT_Folder/myfile.txt

The user can then just directly access the file on a NT server. 

One warning, writing to the QNTC system is pretty slow. You might get a lot
better performance writing to the IFS and letting the user pull from
NETSERVER.

In either case, you must have NETSERVER setup on your system.

This capability provides us with the ability to seamlessly write data from
an ILE RPG program and, also, read text data directly from a IFS or NT
drive.

The only catch here is that you must configure NETSERVER and write to the
UNIX API's which takes some work.

As an alternative, I have written a service program and, I believe many
other people, that hides all the complexity of the Unix API's. For example,

 c                   eval      ehResult = OpenIFSFile(cFilePath:      
 c                                                    (O_CREAT +      
 c                                                     O_CODEPAGE +   
 c                                                     O_RDWR):       
 c                                                     FileHandle1:   
 c                                                     (S_IRWXU +     
 c                                                      S_IROTH):     
 c                                                     cCodePage) 
    
 c                   eval      ehResult = WriteIFsFile(FileHandle1:    
 c                                                     Yes:            
 c                               %editc(Counter:'X') + cRecord2)       

 c                   eval      ehResult = CloseIFSFile(FileHandle1) 

 c                   eval      ehResult = ReadIFSFile(FileHandle1:   
 c                                                    RtnEOF:        
 c                                                    RtnString:     
 c                                                    RtnStringLen)

I would be glad to share the code for this service program with some
examples of how to use them. If you are interested, please send me an e-mail
directly.

I definitely would not recommend trying to build your own functions in less
you have some time to burn and experience with "C" type functions. The Unix
API's are not extremely complex but building the functions is not trivial. I
ended up spending two weeks building and debugging them. Others who had more
"C" experience may have done it quicker.

That investment in time has been paid back many times over. At the time I
wrote them, I only had an example from Midrange that had the code for doing
the writes embedded in a program. Today we have a lot more functions
available. 

When I can, I try to reuse the code other have already built as much as
possible.

Just wish we had a web site and a set of protocals in place like the Open
Source community to build a library of standard functions. Different people
submit code and a working group goes through and arrives at a single set of
code and objects that is published so they can be debug and enhanced in one
place. 

I know there are multiple sites setup to provide RPG code but each
represents different version of functions and there is no set of common
functions like the "C" function libraries. 

Anyway, my two cents.

Thanks

Subject: Transfer of File from PC to AS400


                Please, could anybody tell me if it is possible to transfer
data from a PC file from within an RPG ILE.
                The intention is for it to be seamless for user (ie, not
using the Transfer from PC function of Client Access), and preferably
straight from a network drive, not an AS400 folder.

                Bearing in mind the "RTM" epithet, suggestions of where to
look would be greatly appreciated, not necessarily hand holding.

                Thanks in advance

                Chris
