Re: Reading Files

That depends on whether you share the open data path when you open the file
(the SHARE on either the CRTPF/LF or OVRDBF commands). If a file is opened
with SHARE(*YES) then if program A has read say the first record in the
file, if you then call program B and read the same file it will read the
SECOND record. Specifying SHARE(*YES) can be more efficient, but you need
to design your system so as to allow for the previous scenario. If ni your
case the file is opened SHARE(*NO) then when you issue your first read, yes
it will read the first record in the file, in terms of either the key or
the RRN, depending on how the file is defined in the RPG.
