INTER-LANGUAGE CONNECTION SYSTEM

PURPOSE:To connect a FORTRAN program and a C program by constituting a system in such a way that an option string required in calling a FORTRAN start-up routine from a C start-up routine is transferred. CONSTITUTION:First, control is transferred from an operating system 3 to the C start-up routine 4, and then control is transferred to the FORTRAN start-up routine 5. At that time, the option string is also transferred from the routine 4 to the routine 5. The option string and control are successively transferred to an option analysis C program 6 and the program 6 operates so that it option-analyzes the option string. Thus, option analysis can be executed on a program 2 being a sub-routine even if its under the system that the option string that the C program 2 requires cannot be transferred to the routine 5.
