Method and system are provided for providing instructions to a mainframe system. The method at a client system includes constructing a job control language (JCL) job embedded with an interpreted language program to provide instructions to a mainframe operating system. The method at a mainframe system includes: receiving a job control language (JCL) job embedded with an interpreted language program to provide instructions to a mainframe operating system; copying the interpreted language program to a transient executable area; and executing the interpreted language program.

Providing instructions to a mainframe system

A method, system, and computer program product are provided for protecting state data of computer system code. The computer system code may be operating system code, subsystem code or application code and the item of state data is not expected to change within the execution of the computer system code. The method includes: creating or modifying an item of state data having a field value and being stored in memory for access by computer system code; registering an item of state data for protection; preserving the field value of the item of state data in a form inaccessible to third party software; validating the field value of the item of state data by comparing a current field value with the preserved field value to determine if the field value has been modified; and, if the field value has been modified, taking appropriate action.

An apparatus and program product for automatically deriving a command for starting a program in an operating system of a computer, the method comprising the steps of: identifying an address space provided by an operating system; identifying a program in the address space; searching data logged by the operating system as a result of processing the identified program to identify a start command for initiating processing of the identified program; and outputting the identified start command.
