How to allocate an HFS file from MVS

Can anyone tell me how to allocate an HFS file from MVS.

This is how I allocate a PDSE

SIGNAL ON HALT
DSNIN = 'SYS1.PDSE.DATA(USERINFO)'
'ALLOCATE DA('DSNIN') FILE(INFILE) SHR'
ADDRESS MVS 'EXECIO * DISKR INFILE ( STEM 'USERS.' FINIS )'
'FREE FILE(INFILE)'

I'd like to use the same format to read a sequential file on LPARNAME\var\log\syslog.log

Any suggestions?

Thanks in advance

Read the manuals
starting from.....
http://www-03.ibm.com/servers/eserver/zseries/zos/bkserv/index.html#other_pubs

chose Your os/390 ... z/os release

here is the sequence for os/390 2.9 ( the others follow the same logic )

...and finally land to
OS/390 V2R9.0 Using REXX and OS/390 UNIX System Services

I understand RTFM sir.

My ask was for any suggestions. This being an information exchange forum. I was hoping for someone to say "I've done it this way", watch out for this etc....

Ok, that didn't come out right...

Thanks for the url's I have them all.

I'm a sys prog, but on the comms side.

Just looking for best practice

thanks

When accessing HFS files You should consider whether their organization is
MVS-like/record-oriented or UNIX-like/stream-oriented...

in the first case EXECIO can be used ...
the ALLOC must be written as..
Address TSO "ALLOC FI(mydd) PATH(mypath)... " ,
"other USS dependent parameters"

for UNIX-like like files EXECIO will not work,
consider using the "REXX stream I/O function package"
