ABSTRACT:
A method and system are disclosed in a first data processing system for processing a first instruction in response to an initiation of processing of a second instruction in an emulation environment. The first data processing system includes a first architecture, a first processing environment, and an emulation environment. The first instruction is executable within the first processing environment. The emulation environment is generated by the first architecture. The emulation environment emulates a second data processing system. The second data processing system includes a second architecture and a second processing environment. The second instruction is executable within the second processing environment. A file is established within the emulation environment. The file includes a plurality of routines. Each routine is associated with one of the second plurality of instructions. One of the routines is associated with the second instruction. The routine associated with the second instruction includes an indication of the first instruction and parameters associated with the second instruction. The emulation environment initiates processing of the second instruction, and thereby processes one of the routines. In response to the initiation, the processing of the second instruction by the emulation environment is temporarily halted. The routine associated with the second instruction invokes processing of the first instruction utilizing the parameters stored in the associated routine by the first processing environment.
