guide_mod.F90 @ 2125

Last change on this file since 2125 was 2124, checked in by lguez, 10 years ago

In guide_main, there is the line:

f_out=((MOD(itau,iguide_sav).EQ.0).AND.guide_sav)

The Fortran standard says that the result of mod(a, p) with p = 0 is
processor dependent. With ifort (on Ada at IDRIS), it produces a
run-time error. This is now fixed. The user must still choose
iguide_sav=0 in order to write only once.
