Hi, I'm looking for information on how to access database record
files, and modify them using either SQl or raw access on the AS/400,
however, I've found myself rather baffled by the lack of
documentation, and google doesn't seem to help (me) much...

anyone has info on this?

Thanks in advance!

The following document describes imbedded SQL programming using the SQL
precompilers. This book is for V6R1 but the book exists in prior
releases as well. Look in the IBM i Info Center, Programming,
Programming Languages, SQL.

http://publib.boulder.ibm.com/infocenter/iseries/v6r1m0/topic/rzajp/rzajp.pdf


The _R functions (_Ropen(), _Rclose(), _Rreadn(), _Rwrite(), etc.)
declared in the <recio.h> header file can be used to do 'raw access' to
a database file. They are documented within the ILE C/C++ Runtime
Library Functions manual (V6R1 -
http://publib.boulder.ibm.com/infocenter/iseries/v6r1m0/topic/apis/sc415607.pdf).
