Lal,

The INLIST() function doesn't like a vbl like your supplying. For instance,

lcList = ["A","B","C"]

*--This will return 0 records
SELE * FROM CUSTOMERS WHERE INLIST(custno, lcList)

*--Using macro expansion, like this, rtns the results that you're looking for.
SELE * FROM CUSTOMERS WHERE INLIST(custno, &lc_List.)
