CL is not the best language for working with files - it has always been
kludgy, and this is just an example. I'm not even sure it is solved with
allowing more than one DCLF in more recent releases. So to get this done
in a single program, do it the right way - JAVA!! Just kidding - RPG. Do
the CPYSPLF in the CLLE module, then read the file in an RPGLE module -
use CALLPRC - very easy - and use CRTPGM to link the 2 modules into one
program - then you have your "single program" solution.

The workaround leads me back to my first problem. If I do not hit end of

file, the file remains locked and I cannot overlay it with the next spool
file. The CLOF command does not seem to release the file as I would expect
it to. When EOF is reached, the copy of the next splf does work properly.
Pseudo code below. I know there is the option of splitting it into 2
programs, but seems to me it should work within 1.

WRKSPLF to *print

Copy splf to FILE1

Loop1

RCVF FILE1

Copy splf to FILE2

Loop2

RCVF FILE2

QCLSCAN for string

If string found

Delete splf

CLOF FILE2

Goto Loop1

Else

Goto Loop2

CLOF FILE2

Goto Loop1

There is a workaround for this problem. You can do a RTVMBRD and get
the number of records in the file. Knowing that, you can read the file
in a DOFOR group and avoid hitting the end of file. It can then be
repositioned and read a second time.

I think you may need to create a second CL program to do the file2
processing. I think that hitting eof in a rcvf loop in CL cannot be
reset.

I have a CL program which does a WRKSPLF to an outfile, then copies the
outfile to a PF.

The CL loops thru each record of the first PF, and copies the splf to a
second PF and reads thru this second splf looking for a string. At EOF
on the second PF, or when the string is found, I want to process the
next record in the first PF.

When I find the string:

if I exit the loop, then attempt to copy the next splf to the second
PF, I get an error message the file is locked, even though I've done a
CLOF on the second PF.

if I continue reading to EOF, I can copy the next splf to the second
PF, but I'm stilled positioned at the EOF. POSDBF is not positioning to
the beginnign of the file.

Is there any way around this situation.

I've searched the archives, found where this has been posted before but
not a solution. I do see reference to Scott having an explanation to
this but I cannot find his explanation.

Thanks

Ron
