Abstract
Abstract An argument which is a set consisting a global variable in a procedure to be called, a designation symbol representing localization and a variable or constant on a procedure call side is designated as an argument of a procedure call statement of a program, the global variable in the called procedure is localized in the procedure in response to the designated information, and the value of the variable on the procedure call side which is a member of the set is used as the initial value of the local variable. An argument which is a set consisting of a local variable in a procedure to be called, a designation symbol representing globalization and a variable on a procedure call side is designated as an argument of a procedure call statement of a call program, the local variable in the called procedure is globalized in response to the designation information, and a data area which is the same as that of the variable on the procedure call side, which is a member of the set, is used. A procedure call statement is designated by omitting an argument of a procedure call statement of a call program, the omitted argument in the procedure is processed as a global variable, and a data area which is the same as that of a variable on the procedure call side, which has the same name as that of the argument in the procedure, is used.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
131 words
In a method of procedure linkage control including a first procedure for executing a first processing stage and a second procedure for executing a second processing stage by utilizing the result of processing of said first procedure, a method of procedures linkage control characterized in that a first variable used in said first procedure and a first variable used in said second procedure are regarded as being different variables and said first procedure is called using the value of a second variable as the value of said first variable used in said first procedure in response to a designation symbol when said designation symbol, said first variable to be used in common for both of said first and second procedures and said second variable used in said second procedures are designated.
Claim 2
Dependent Claim
131 words
In a method of procedure linkage control including a first procedure for executing a first processing stage and a second procedure for executing a second processing stage by utilizing the result of processing of said first procedure, a method of procedures linkage control characterized in that a first variable used in said first procedure and a first variable used in said second procedure are regarded as being different variables and said first procedure is called using the value of a second variable as the value of said first variable used in said first procedure in response to a designation symbol when said designation symbol, said first variable to be used in common for both of said first and second procedures and said second variable used in said second procedures are designated.
Claim 3
Dependent Claim
71 words
A method of procedures linkage control according to claim 1 wherein a first data memory area for storing the value of a variable is assigned to said first variable used in said first procedure separately from said first variable used in said second procedure when said first procedure is called, and the content of a second data memory area for said second variable is copied to said first data memory area.
Claim 4
Dependent Claim
48 words
A method of procedures linkage control according to claim 2 wherein said data memory area for storing the value for said variable is assigned to a data memory area which is the same as said data memory area for said second variable when said first procedure is called.
Claim 5
Dependent Claim
89 words
In a method of procedures linkage control including a first procedure for executing a first processing and a second procedure for executing a second processing by utilizing the result of processing of said first procedure, a method of procedures linkage control characterized in that said second procedure calls said first procedures by regarding a first variable as a second variable in response to a designation symbol when said first variable used in said first procedure, said designation symbol and said second variable used in said second procedure are designated.
Claim 6
Dependent Claim
89 words
In a method of procedures linkage control including a first procedure for executing a first processing and a second procedure for executing a second processing by utilizing the result of processing of said first procedure, a method of procedures linkage control characterized in that said second procedure calls said first procedures by regarding a first variable as a second variable in response to a designation symbol when said first variable used in said first procedure, said designation symbol and said second variable used in said second procedure are designated.
Claim 7
Dependent Claim
141 words
In a method of procedures linkage control including a first procedure for executing a first processing and a second procedure for executing a second processing by utilizing the result of processing of said first procedure, said first procedure having a first variable used for executing said first processing, said second procedure having a second variable used for executing said second processing, both of said first and second variables having the same name, but said first variable being regarded as a different variable designated when said first procedure is called and being used for said first procedure, a method of procedures linkage control characterized in that said first variable is regarded as a variable which is the same as said second variable and said first procedure is called unless a variable is designated at the time of call of said first procedure.
Claim 8
Dependent Claim
141 words
In a method of procedures linkage control including a first procedure for executing a first processing and a second procedure for executing a second processing by utilizing the result of processing of said first procedure, said first procedure having a first variable used for executing said first processing, said second procedure having a second variable used for executing said second processing, both of said first and second variables having the same name, but said first variable being regarded as a different variable designated when said first procedure is called and being used for said first procedure, a method of procedures linkage control characterized in that said first variable is regarded as a variable which is the same as said second variable and said first procedure is called unless a variable is designated at the time of call of said first procedure.
Claim 9
Dependent Claim
57 words
A method of procedures linkage control according to claim 5 wherein a data memory area for storing the value for said second variable is assigned to a data memory area which is the same as a data memory area for said second variable unless a variable is designated at the time of call of said first procedure.
