6. TYPICAL RUNNING TIME

NEA-DB executed the test case on IBM 3033 in 700 seconds.
NEA 0704/01: After minor syntax corrections the program was re- compiled using FORTRAN-77 compilers on VAX 6000-510 and IBM 3090 computers. The execution of the test case required 22 seconds on the VAX and 23 seconds on the IBM.
