VIEW OPERAND FOR CREATING A VIEW OF AN EXPANSE FILE
A method for processing an operand by an operating system includes receiving, at the operating system, a set of interrupts from a view operand; wherein a first interrupt causes the operating system to create a postern, a second interrupt causes the operating system to delete a specified postern and the remaining interrupts are transformed into a user status that is placed in the operand. A non-transitory machine readable memory medium including instructions when executed to cause a processor to perform the following actions: receiving, at the operating system, a set of interrupts from a view operand; wherein a first interrupt causes the operating system to create a postern, a second interrupt causes the operating system to delete a specified postern and the remaining interrupts are transformed into a user status that is placed in the operand.
1 . A method of processing an operand by an operating system, the method comprising:
receiving, at the operating system, a set of interrupts from a view operand;
wherein a first interrupt causes the operating system to create a postern, a second interrupt causes the operating system to delete a specified postern and the remaining interrupts are transformed into a user status that is placed in the operand.
2 . The method of claim 1 wherein the view operand includes a space starting subset distance from the beginning of a data expanse file.
3 . The method of claim 2 , wherein when the operating creates a postern, it creates a postern bank and returns an address of the bank to a database management system.
4 . The method of claim 1 , wherein the view operand includes a number of words.
5 . The method of claim 4 , wherein the number of words can be 2**60 words of virtual or physical space.
6 . The method of claim 1 , wherein the view operand includes a postern upper limit.
7 . The method of claim 7 , wherein the view operand includes a postern lower limit.
8 . The method of claim 1 , wherein the postern can loaded to a base register.
9 . The method of claim 1 , wherein the user status is placed into a word 7 of the view operand.
10 . A non-transitory machine readable memory medium including instructions when executed to cause a processor to perform the following actions:
receiving, at the operating system, a set of interrupts from a view operand;
wherein a first interrupt causes the operating system to create a postern, a second interrupt causes the operating system to delete a specified postern and the remaining interrupts are transformed into a user status that is placed in the operand.
11 . The non-transitory machine readable memory medium of claim 10 wherein the view operand includes a space starting subset distance from the beginning of a data expanse file.
12 . The non-transitory machine readable memory medium of claim 11 , wherein when the operating creates a postern, it creates a postern bank and returns an address of the bank to a database management system.
13 . The non-transitory machine readable memory medium of claim 11 , wherein the view operand includes a number of words.
14 . The non-transitory machine readable memory medium of claim 13 , wherein the number of words can be 2**60 words of virtual or physical space.
15 . The non-transitory machine readable memory medium of claim 10 , wherein the view operand includes a postern upper limit.
16 . The non-transitory machine readable memory medium of claim 15 , wherein the view operand includes a postern lower limit.
17 . The non-transitory machine readable memory medium of claim 10 , wherein the postern can loaded to a base register.
18 . The non-transitory machine readable memory medium of claim 10 , wherein the user status is placed into a word 7 of the view operand.
