I am passingly familiar with C on the AS/400, and use it for utility-type 
stuff (especially with IFS files).  A colleague of mine is fluent in C, and 
would like to read an externally described file using _Rreadf, etc.  We can 
get the file to open and actually print the buffer (fp->in-buf).  Is there 
an easy way to map this buffer to the externally described field specs, or 
do we have to manually describe the structure?  The C manual is less than 
illuminating...
