Input/output operations in an information processing system

摘要

In an information processing system, a method to perform I/O (Input/Output) operations for an interpretative based program that is executing on an Interpretative Machine (IM). The method comprises the steps of: executing an interpretative based program on an Interpretative Machine (IM); receiving a request to pass data of unknown length out of the program; allocating a local buffer in the information processing unit to write the data of unknown length; writing the data of unknown length to the local buffer; determining the size of the data of unknown length in the local buffer; and passing the length of the data combined with the data in the buffer out of the program. In accordance with another aspect of the invention, a computer readable medium is described to carry out the above method.
