Section 1 - Externally Described Files in Programs (14%)
Use printer files and "O" specs to define output in a program
Use database file I/O operations in a program
Grab one particular record in a file:
chain (employee) empfile;
Write a record:
write roperator;
Set the pointer to a spot in the file then read all records that match the key:
setll (employee) emphist;
reade (employee) emphist;
dow not %eof();
::: Logic here :::
reade (employee) emphist;
enddo;
