# NAG Library Routine DocumentD02MCF

Note:  before using this routine, please read the Users' Note for your implementation to check the interpretation of bold italicised terms and other implementation-dependent details.

## 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.

## 4  References

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.

None.
