Have you tried xHarbour?
Such printing uses normal file API. In xHarbour Maurilio changed open()
function used by hb_fsOpen() to OS2 API DosOpen() combined with _imphandle()

* source/rtl/filesys.c
+ added HB_OS2_IO sections to work around a GCC 'feature' on OS/2
which makes it fail to open/create files on filesystems which do
not support extended attributes (EAs).
It's possible that this modification resolves the problem.
Anyhow if possible I would like to also ask you to make tests
with file range locking with Harbour and xHarbour. F.e. try
to check if RLOCK set by one process is visible by other, f.e.
in this code:
proc main()
if !dbExists("_tst")
? "Create table"
dbCreate("_tst",{{"F1","C",1,0}})
use _tst
dbappend()
close
endif
use _tst shared
dbgoto(1)
? "Locking record 1:", dbRlock()
inkey(0)
return
I'm not OS2 user/programmer and it's not clear for me reading OS2
API if it is possible to set file range locking without HLockID handler
returned by DosProtectOpen(). If _imphandle() cannot retrieve it
internally from OS structures then probably not.
If locking works correctly in xHarbour then I'll add Maurilio's
modifications to Harbour OS2/GCC builds.
best regards,
