RE: X-Spec (was: "RPG isn't cool")

[Bob Crothers <bob@xxxxxxxxxxxxxx>]

I am not looking for "low level" file IO, but high level!  Eg: Declare 
the file, use the file.  Like in RPG.  To do Native database IO in 
ILE/C this is what you have to do:

        // Below  "Declares the file".  Equivilent to an "F" spec in RPG
#pragma mapinc("xfimghp", "*libl/xfimghp(*all)", \
                          "both key lvlchk", "d")
#include "xfimghp"

_RFILE                  *imghpf;    /* XFIMGHP */
_RIOFB_T             *imghpfbk;

        // The below "Opens the file".  Equivilent to "OPEN XFIMGHP" in RPG

imghpf = _Ropen("*libl/xfimghp",  "rr, arrseq=N, blkrcd=Y"); 

if (imghpf == NULL)
  {
  printf("Error opening XFIMGHP - %s\n", XlateErrorNo(tBuf, errno));
  return;
  }

        // Below are the actual record buffers.  RPG "I" spec

FAXLIB_XFIMGHP_XFIMGHR_both_t  imghp;
FAXLIB_XFIMGHP_XFIMGHR_key_t   imghpKey;

        // Below does a "Chain"
                // cpystrchar converts "C" style string (null terminated) to 
AS/400 
fixed length char buffer

cpystrchar(imghpKey.IMNAME, hgi->ImageName, sizeof(imghpKey.IMNAME));

imghpfbk = _Rreadk(imghpf, &imghp, sizeof(imghp), __KEY_EQ | 
__NO_LOCK,
                   &imghpKey, sizeof(imghpKey));

if (imghpfbk->num_bytes != sizeof(imghp))
  ImgNotFoundFlag = TRUE;                       // Record not found (probably)


None of the above is rocket science, but it sure is a pain where the 
sun don't shine!

Not a bad idea.  How many out there think that low level file io in C 
is as
easy as RPG?  How about stream file io?

Instead of making RPG more like C, how about making C more like RPG?

Before everybody starts throwing flaming emails, stop and think about
it.

What is the best part of RPG?  The Database IO.  In RPG, it So easy to 
use and very effective.

What is the bad part of RPG?  The fixed form and highly structured
stuff.  Short names.  Etc.

What is the good part of "C"?  Highly flexible, free form, multiple
data types, and stuff like that.  What RPG is bad at.

What is the bad part of "C"?  Database!  The database support, well it 
sucks.  Hard to use...hard to manage...and harder to figure out!

But, the rest of "C" is very good.  And, it is not hard for an RPG
programmer to learn C.

Then you don't have to worry about "breaking" RPG.  And to give
descent Database to C, you only have to add some functions.

Just a thought...I'll go back into lurk mode.
