Fortran NEQNF routine :handling error

Fortran NEQNF routine :handling error

Fortran NEQNF routine :handling error

I am using the IMSL Math special function DNEQNF to solve  a nonlinear system. This function stops the program when error 3 occurs exiting with the following error message :
'the iteration has not made good progress.
The user may try a new initial guess.
Stop - Program Terminated'
I would like that this error do not stop the program.
I was not able to do so with the routines ERSET, IERCD or N1RTY.
where do I should include them in the program with respect to the routine DNEQNF to achive my goal? Is there something I am missing?

I appreciate your help
Thank you
