Dennis,

Not sure that's true....at least given how I understand the
docs...._rreadk offers the __KEY_NEXTEQ parm value:
__KEY_NEXTEQ
Positions to and reads the next record that has a key equal to the
key value at the current position. The key parameter is ignored.

Thus it seems to me that _rreadk could be used in place of an RPG
READE or an RPG CHAIN, but I'm trying to confirm.

You want _rreadn()

Http://publib.boulder.ibm.com/infocenter/iadthelp/v7r0/index.jsp?topic=/com.ibm.etools.iseries.langref.doc/rzan5mst225.html - search for _rreadn.  _rreadk does not honor the current cursor position, although you could kinda-sorta emulate that (assuming there is some uniqueness).

All,

Little confused...(and I haven't been gone that long! )

_ropen() to open a record file
_rlocate() to position to a particular key (SETLL?)
_rreadk() to read by key  (CHAIN or READE?)
_rreadm() to read next (READ?)

if I want to read a set of records with a certain key, do I need to
call _rlocate() followed by _rreadK() in a loop or can I use
_rreadn()?

Not I'll be dealing with a partial key...

Thanks!
Charles
