Re: Spl2stmf and HPT

Given the name, I assume that xbufspc_p is a pointer to some bit of
memory...

So you need to to not look at the value in xbufspc_p, but at the memory
it's pointing to..

Is there an xubfspc variable already you can refer to?

If not, this should work, but you'll need to size it suitably...
dcl-s mydata char(xxxx) based(xbufspc_p);

Unless the pointer is to a user space or otherwise to large for RPG.

In that case you could use memcpy to copy blocks from the pointer to your
own buffer.

All of the examples I've found take the pointer and give it to another
function like write to the IFS, create a duplicate spool file.

I want to get the spool file data into memory, look for a keyword, then do
some stuff based on whether the keyword exists.

How can I change this line so that I can have the data in the program to do
a %SCAN?

EVAL bytesw = write(fd : xbufspc_p : hptxbuflena)

Thanks, Jack

The output of HPT is usually some flavor of ASCII. Maybe that's why it
looks like "gibberish" to you?

Possibly you just need to mark the IFS file with a proper CCSID after it's
done, and tools like DSPF or EDTF will view it properly?

Regarding your change... are you certain that the data is null-terminated?
In my experience with the HPT API, it normally is not, it's just raw binary
data. You should not be using %STR here... unless I'm misunderstanding.

I downloaded a program called Spl2Stmf that uses the spool file API's
to read a spool file and write an IFS file.

I'm trying to modify so I can just read the spool file in RPG to look
for some keywords.

I changed this line which wrote the STMF:

EVAL bytesw = write(fd : xbufspc_p : hptxbuflena)
To this:
String = %str(xbufspc_p : hptxbuflena);

But I only see gibberish in the String. I'm guessing that the write
command in the original example did some conversion when it wrote to the

IFS.

Any ideas what I'm doing wrong? Maybe I need to strip out the HPT
completely as I'm just reading the spool file in the program? The
original download save file link is broken however.

Now that I think more this is overkill and I just need something to
open and read the spool file.
