Abstract

Method and system for processing an interpretable program having calls to a separately compiled procedure is described. The interpreter uses a predefined signature file (SIGFILE) to identify the arguments and result of the separately compiled procedure. The interpreter then generates source code for a call file (CALLFILE) from the information in the signature file. The CALLFILE procedure accepts the arguments for the separately compiled procedure from the interpreter and passes the arguments to the separately compiled procedure. The result, if any, of the separately compiled procedure is returned to the CALLFILE which in turn returns the result to the interpreter. A CALLFILE procedure may be used for more than one separately compiled procedure by passing in the address of the particular separately compiled procedure which is to be called.
