1 Purpose

D02MCF is a setup routine which must be called prior to a continuation call to D02NEF.

2 Specification

SUBROUTINE D02MCF (

ICOM)

INTEGER

ICOM(15)

3 Description

D02MCF is provided to permit you to signal that the next call to D02NEF is a continuation call. In particular, if D02NEF exits because the maximum number of integration steps has been exceeded, then a call to D02MCF resets the step counter allowing the integration to proceed.

See Section 3 in D02NEF.

5 Parameters

1: ICOM( $15$ ) – INTEGER arrayCommunication Array: This must be the same array ICOM as passed to the integration routine D02NEF; D02MCF does not require access to all of that array, hence the smaller dimension given here.

On entry: contains details of the current state of integration as returned by D02NEF.

On exit: one or more of the values is changed to signal to the integrator that a continuation call is being made. This will reset the step counter to zero.
