What does Implicit Open means with respect to a file ? What
about the Explicit Open?..what are the major differences
between these two?

Answer

Imlicit open means file is open by program which is automaticaly done whne we call a program .
Explicit open means you open a file thorugh f-specification keyword "usropn " and then open and close the file means in explicit open the authority of opening and closing the file is done by programmer according to the requirements.
this is also the basic diffreence .

SO AFTER READING RECORD 20 IT GOES TO 30 BUT WE ARE SEARCHING FOR 25 WHICH IS NOT PRESENT SO IT WILL RETURN 20 AND OUTPUT
MEANS IF FIELD HAVING DATA LIKE : 10,20,24,30,40
THEN IN THIS TIME OUTPUT WILL ME 24 OK BYE T.C
