Hi,
The AT END and NOT AT END clause is used with READ command
Plz refer the command below:
READ filename....
AT END
STMT 1
STMT 2
NOT AT END
STMT 1
STMT 2
...
END-READ
at end clause is used to perform some statements or paras when the EOF or end of file occurs.
so goes for not at end
generally at end is used, not at end is not much used, but it can be used all the same.
we can give statements to perform or we can give para names etc
hope it helps |
