Restrictions on the Use of PAR.

The array PAR in the user-supplied routines is available for equation parameters that the user wants to vary at some point in the computations. In any particular computation the free parameter(s) must be designated in ICP; see Section 10.7. The following restrictions apply :

-

The maximum number of parameters, NPARX in auto/07p/include/auto.h, has pre-defined value NPARX=36. NPARX should not normally be increased and it should never be decreased. Any increase of NPARX must be followed by recompilation of AUTO.

-

Generally one should only use PAR(1)-PAR(9) for equation parameters, as AUTO may need the other components internally.
