Answer to each part of the question should be confined to about 300 words.

Question 1:

36-50 Client Phone
51-70 Business Volume
71-72 Status (Project is On, Project is over, Negotiation for project is on, Clients having bad track record etc.)
73-80 Not used

The created relative file should be used for the following searching:
To ascertain the status of a client, prior to a project negotiation.
To display the contact phone of a client.

Write the COBOL program for the above.

Question 2:
