14. OTHER PROGRAMMING OR OPERATING INFORMATION OR RESTRICTIONS
moving ASTEM to the CDC6600 the variable argument list calls to
the CONU subroutine were converted to fixed to conform to CDC
conventions, and double-precision data statements and arithmetic
functions were changed to single-precision. The rounded
arithmetic option of the FTN compiler was necessary for execution
of the sample problem on the CDC7600. To relieve convergence
failure in subroutine ROOT during CDC executions, the convergence
criterion may be relaxed, but with caution.
The output values from the PROPS routine are returned through
the labeled COMMON block /CPROPS/. When using PROPS in
conjunction with the ASTEM routines, a "larger" H or H-extended
compiler is needed requiring 450K at SYSGEN time. The G and G1
compilers will compile in a normal region. These compilers,
however, will delete some of the beginning comments of the ASTEM
routine BINOMX, as there are more than 30 consecutive comments.
Variables passed to PROPS must be either non-zero (INPUT) or zero.
