Hi, simple script: <hansl> set verbose off # mpi --send-functions --np=$sysinfo.mpimax/2     scalar mpisize = $mpisize     loop for i=0..mpisize --quiet         if $mpirank == i             printf("I'm node no. %d in loop 1\n", $mpirank)         endif            endloop     loop for i=0..$mpisize --quiet         if $mpirank == i             printf("I'm node no. %d in loop 1\n", $mpirank)         endif            endloop end mpi </hansl> Why the first loop works and the second one does not?
