C Example 1
Set characteristics for a select search: BOOL fOK
BOOL fOK;
int iSession;
...
fOK = LceSetSelectOptions(iSession,
...
"*BACKWARDS, *MAXREC25");
...
fOK = LceRequestSelect(iSession,
...
"SURNAME,
...
SALARY",
...
"PSLMST",
...
"",
...
FALSE);
...
fOK = LceReceiveSelect(iSession,
...
"PSLMST");

fOK = LceGetRecordCount(iSession,
...
"PSLMST",
...
&iRecords);
...
for (iCount=0;
...
iCount < iRecords; i++)
{
...
fOK = LceGetSelect(iSession,
...
"PSLMST",
...
iCount,

C Example 2
Lock a record during a fetch: BOOL fOK
BOOL fOK;
int iSession;
...
fOK = LceSetSelectOptions(iSession,
...
"*LOCK");

C Example 3
Use *RECEIVEIMMED to Select Records: BOOL fOK
BOOL fOK;
int iSession;
