Abstract
A method and system is provided for attaching user defined information to a process object in a data processing system. The method comprises creating a process control block corresponding to an invoked process. The control block has system defined process variables that are assigned values by the operating system. The method further comprises defining a user defined process variable in the process control block, and assigning a value to the user defined process variable.
Claims26
A method for attaching user defined information to a process object in a data processing system, the method comprising the steps of:
- invoking a first process;
- creating a control block corresponding to the first process, wherein the control block has system defined process variables that are assigned values by the operating system;
- searching for an undefined process variable field in the process control block for the first process, after the first process has been invoked;
- if an undefined process variable field is found, defining a User Defined Process Variable in the undefined process variable field;
- and
- assigning a value to a User Defined Process Variable in the control block corresponding to the first process.
A data processing system for attaching user defined information to a process object, the data processing system comprising:
- means for invoking a first process;
- means for creating a control block corresponding to the first process, wherein the control block has system defined process variables that are assigned values by the operating system;
- means for searching for an undefined process variable field in the process control block for the first process, after the first process has been invoked;
- means, responsive to locating an undefined process variable field in the process control block corresponding to the first process, for defining a User Defined Process Variable in the undefined process variable field;
- and
- means for assigning a value to a User Defined Process Variable in the control block corresponding to the first process.
