Re: I don't know how to convert these old I specs

This sounds like a multi-format logical file, because you said FIELD1 is in the same position from two different files.
This also means multiple record formats, one from each externally described physical file, you define two "sets" of I-specs, one for each external record format.

FIELD1 is in both PFs in the same position
FIELD2 is in PF1 only.
A 5 character field exists in both formats at position 59.

I_RecdFmt1 _
I ExtFld1 Field1
I ExtFld2 Field2
I ExtFld3 Field3

I_RecdFmt1 _
I ExtFld1 Field1
I ExtFld3 Field3

Hi all,

In this code MYFILE is to become externally described.

IMYFILE NS
I 2 23 FIELD1
I P 39 432FIELD2
I P 59 632FIELD3

MYFILE is a logical based on two physical files.

FIELD1 is in both PFs in the same position
FIELD2 is in PF1 only.
A 5 character field exists in both formats at position 59.


I want to rename the fields after declaring MYFILE as externally described.

I_________
I EXTFL1 FIELD1
I EXTFL2 FIELD2
I ______ FIELD3


What format name do I use? How do I know which is the external name for FIELD3?

Thanks.
