Re: Spl2stmf and HPT

Charles,

The SPL2STMF command that the OP is referring to is a program that feeds a spooled file into the IBM-supplied Host Print TRansform API, and writes the output to a stream file.

So, yes, HPT normally comes into play when a spooled file is printed. But, in this case, he's invoking it directly.

Scott,

Correct me if I'm wrong...but doesn't HPT come into play between the spool
file and the printer?

In other words, the data in the spool file he is reading should be an
EBCDIC *SCS or *AFPDS stream. HPT would read that and send it to the
printer.

So Jack shouldn't have to worry about EBCDIC --> ASCII unless the spool
file he is trying to read is of type *USERASCII

What HPT does is convert the spooled file into the language of the
printer. How easy/hard that is to read from your RPG program will
depend on which WSCST definition you are using. Some are very simple
and produce a plain text file, others do not.

But, yes, assuming you have the right WSCST setup, the output of the HPT
API can be plain text, just load it into a variable and then do your
%SCAN.

You'll either need to scan for an ASCII string, or translate the spooled
file to EBCDIC, of course.

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.
