Abstract
An image forming apparatus has a first execution environment that can interpret and execute a first-format instruction for controlling the image forming apparatus, and a second execution environment that can interpret and execute a second-format instruction defined by a format that does not depend on a type of the image forming apparatus, realized in the first execution environment. The image forming apparatus includes control means for controlling processing of starting execution of the first-format instruction from the second execution environment, using a second-format predetermined instruction, recognition means for recognizing, when interpreting the second-format instruction by executing application software in the second execution environment, whether or not an instruction string to be executed is the second-format predetermined instruction, and control means for controlling the image forming apparatus by starting and executing the first-format instruction via the second-format predetermined instruction when the recognition means has recognized that the instruction to be executed is the second-format predetermined instruction, and for controlling the image forming apparatus s…
