Hi everyone
I just re-read my e-mail and realized that it is misleading
Using that web site -
A better way to read a file in the IFS with RPG @ RPGPGM.COM<https://www.rpgpgm.com/2016/03/a-better-way-to-read-file-in-ifs-with.html>
The problem is with the the OpenFile

Here is the pertinent code

dcl-pr OpenFile pointer extproc('_C_IFS_fopen') ;
*n pointer value ; //File name
*n pointer value ; //File mode
end-pr ;

dcl-pr ReadFile pointer extproc('_C_IFS_fgets') ;
*n pointer value ; //Retrieved data
*n int(10) value ; //Data size
*n pointer value ; //Misc pointer
end-pr ;

dcl-pr CloseFile extproc('_C_IFS_fclose') ;
*n pointer value ; //Misc pointer
end-pr ;


PathFile2read = %trim(PriorPathfile) + x'00' ;
OpenMode = 'r' + x'00' ;
FilePtr = OpenFile(%addr(PathFile2read):%addr(OpenMode)) ;

if (FilePtr = *null) ;
CannotreadPriorBAI2();
return;
endif ;

Subject: Using _C_IFS_fopen and _C_IFS_fgets to read files in the ifs

Hi everyone
We are on V7r3
We have a number of files in the ifs that I am attempting to use _C_IFS_fopen, _C_IFS_fgets and _C_IFS_fclose to read
Please see the following web page
A better way to read a file in the IFS with RPG @ RPGPGM.COM<https://www.rpgpgm.com/2016/03/a-better-way-to-read-file-in-ifs-with.html>

I have a situation where one of the files is not read by these utilities
Does anyone know how I can determine why?
I am able to go into that file using wrklnk and edtf - so I believe its NOT an authority situation

However, the program is not able to read the rest of the files AFTER that one
I can sign off, sign back in, change the program to start AFTER that one particular file, and the rest of the files can be read
So I am assuming that something needs to be initialized after such a read, but In am unable to find anything as to what that could possibly be
Does anyone have any knowledge of such a situation and how to rectify it?

As always - all answers gratefully accepted
