Re: Issue in CPYF

I am using CPYF to copy the contents of a Physical file to a flat file (of 132 bytes in length).
Here the decimal, float and negative data values are not copied properly in the destination (flat file) . Ex 12.34 is copied as 1234 and -5 as 5. Could anyonw help me in solving this? 

Hari -

You're obviously new to this platform. This is documented, expected behavior. 

I'm assuming you are using CPYF with FMTOPT(*NOCHK).

From the help text for CPYF: 

<Help>

*NOCHK If the record formats of the database files are different, the copy operation continues despite the differences. Record data is copied directly (left to right) from one file to the other. *NOCHK is required when copying all record formats from a logical file with more than one format to a physical file that is of the same type (source or data) as the from-file. If this value is specified, null values are ignored and no conversion of
date/time data occurs. 

</Help>

In DB2/400 files, decimal points are assumed and
signs are stored in the low-order half-byte. 

If you understand the statement above from the help text,
neither of them get converted when copied to a flat file.

CPYTOIMPF will put signs and decimal points into the flat file.
However, the values in the signed fields in the in flat file will not be aligned.

Example (CUSMST is a "regular" file, TESTFILE is a "flat" file):

CPYTOIMPF FROMFILE(CUSMST) TOFILE(QTEMP/TESTFILE) DTAFMT(*FIXED)

Here is what a signed field looks like in the output file:

-100.10 999.99 888.88 111.22 888.88 12345.67 00

If this is not what you want in your "flat" file, you may need to write an HLL (HLL = High Level Language) program
to create the flat file in the form you desire.

Good luck,
