One or more processors receive (a) first software written in a first computer language, (b) user input identifying a first name of a first method in a plurality of methods defined in the first software, and (c) user input identifying a location within a second software that is written in a second computer language different from the first computer language. In response, the one or more processors automatically prepare and store at the user-identified location in the second software, a new instruction formatted in a syntax of the second computer language that invokes the first method identified in the first software by the first name. The second software may be initially created with a first instruction to include at least a first additional name (e.g. “main”) used to invoke execution of the second software, and as a parameter thereof a second additional name identifying the first software.
