Method, system, and program for generating a program capable of invoking a flow of operations

Provided are a method, system, and program for generating a program capable of invoking a flow of operations, wherein the program is capable of being initiated from an external call. A definition file defining a flow of operations and mapping information defining input parameters to the flow of operations are received. The received definition file and mapping information are processed to generate program statements within the program that when executed perform: setting input parameters to the flow of operations to values received from an external call to the program; invoking the flow of operations with the input parameters including values from the external call; and receiving output from the flow of operations and extracting at least one value from the received output to return to the external call.
