Exactly. With IMPLICIT NONE one sees that INF is an (implicitly typed) integer
variable, which has an undefined value.
minval = +INF
maxval = -INF
How about:
minval = huge(minval) ! largest finite value
maxval = -huge(minval)! smallest finite value
or shorter (untested)
min = minval(arr( [(1+kcycle*i, i=0,npts-1)] )
max = maxval(arr( [(1+kcycle*i, i=0,npts-1)] )
where (g)Fortran does internally what you want.
