CDIR$ ID "@(#) libfi/mpp_pre/premin_s_2@.f	92.0	10/08/98 14:37:14"
************************************************************************
*
* Purpose:	Find the minimum value of the elements identified by mask,
*		while saving all intermediate results.  This routine handles
*		integer source arrays of rank 2. It returns an array result.
*		This routine is called by the C routine _PREMIN_JS2.
*
* Arguments:	result	- integer array of rank 2.
*		source	- integer array of rank 2.
*		dim	- integer scalar: dimension to search along.
*		mask	- logical array of rank 2.
*		sext	- integer array of rank 1:
*			  extents of the source array.
*
* Variables:	carry	- working variable to save current value of carry
*		init_val- initial value of carry variable
*
* Intrinsic functions called:
*		my_pe()
*		hiidx()
*		lowidx()
*		home()
