increasing optimization cycles in Mopac



Hi,
   I'm trying to do a geometry optimization with Mopac 7.04. The keywords
 I have specified are
 pm3 t=999999.9  ef hess=1 mmok let gnorm=
 However the cacluation does not end properly and I get the error:
 EXCESS NUMBER OF OPTIMIZATION CYCLES
 Looking through the Mopac manual I dont see anyway to increase the
 number of optimization cycles. Does anybody know how can I increase the
 number of cycles so that I can achieve the SCF field?
 Thanks,
