[molpro-user] mxgrp too small in binput

[Andy May]

Paul,

I see where you got the 400 from, but shortly after it's redefined:

c...  give half the memory remaining to stuff dimensioned mxgrp
       mxgrp = min(maxbfn,(icorrm()/2)/(mxprim+mxcont*mxprim+7))

Since maxbfn is by default 4095, it appears the only way mxgrp could be 
lower is if the memory requested was small.

Can you post the input and output files?

Best wishes,

Andy
