The -real
switch tells KAP what the Fortran compiler
default size for REAL variables is in bytes, N, where REAL*N
can be 4 or 8. To change the default size of REAL variables,
for example, from 4 to 8, first, set the Fortran compiler
switch -r=8
. Next, tell KAP the new size with the
-real=8
switch.
