Hai All,

I am unable to understand a small piece of EASYTRIEVE CODE:
Code:

FILE    Persnl    FB(150 1800)
%Persnl
FILE   Sortwrk  FB(150 1800) VIRTUAL
COPY Persnl


My understanding is that

1.File Pernl is FB with 150 bytes why is 1800 declared there - cannot understand.
2.% Persnl is like a copy book i guess
3.File Sortwrk is a temporary File.
4.Copy Persnl - cannot understand

Please help me in understanding.

The COPY statement duplicates the field definitions of a named file to another
file to alleviate re-entering the same definition.
The Persnl in the COPY is the Persnl on the FILE line.

1800 is the BLKSIZE. You should have a value of 0 to allow the block size to be determined by the operating system
