Compilation options

Early in the script you will find such lines as below :

# Fortran compiler options :
# optfrt[3] = Optimal, as  operations    : -g -O0 -Mscalarsse
# optfrt[2] = Debugging                  : -g -O0
# optfrt[1] = Debugging + Bound checking : -g -O0 -C
# optfrt[0] = User-defined options
optfrt[0]=""
#
# Choose subscript (0/1/2/3) :
# --------------------------
Ofrt=3

You can set the value of Ofrt to 1, 2 or 3 (default value) to use a set of recommended pre-defined options for the compilation of Fortran source code.
