STEP2

#define STEP2

Factors a dollar expression. Notation: d->nfactors becomes nonzero. if the number of factors is one, we leave d->factors zero. Otherwise factors is an array of pointers to the factors. These are pointers of the type FACDOLLAR. fd->where pointer to contents in term notation fd->size size of the buffer fd->where points to fd->type DOLNUMBER or DOLTERMS fd->value value if type is DOLNUMBER and it fits in a WORD.

EvalDoLoopArg()

WORD EvalDoLoopArg	(	PHEAD WORD *	arg,
		WORD	par
	)

Evaluates one argument of a do loop. Such an argument is constructed from SNUMBERs DOLLAREXPRESSIONs and possibly DOLLAREXPR2s which indicate factors of the preceding dollar. Hence we have SNUMBER,num DOLLAREXPRESSION,numdollar DOLLAREXPRESSION,numdollar,DOLLAREXPR2,numfactor DOLLAREXPRESSION,numdollar,DOLLAREXPR2,numfactor,DOLLAREXPR2,numfactor etc. Because we have a do-loop at every stage we should have a number. The notation in DOLLAREXPR2 is that >= 0 is number of yet another dollar and < 0 is -n-1 with n the array element or zero. The return value is the (short) number. The routine works its way through the list in a recursive manner.

	)

Definition at line 3558 of file dollar.c.

MakeDollarInteger()

WORD * MakeDollarInteger	(	PHEAD WORD *	bufin,
		WORD **	bufout
	)

For normalizing everything to integers we have to determine for all elements of this argument the LCM of the denominators and the GCD of the numerators. The input argument is in bufin. The number that comes out is the return value. The normalized argument is in bufout.

MakeDollarMod()

WORD * MakeDollarMod	(	PHEAD WORD *	buffer,
		WORD **	bufout
	)

Similar to MakeDollarInteger but now with modulus arithmetic using only a one WORD 'prime'. We make the coefficient of the first term in the argument equal to one. Already the coefficients are taken modulus AN.cmod and AN.ncmod == 1

AddPotModdollar()

void AddPotModdollar

(

WORD

Adds a $-variable specified by numdollar to the list of potentially modified $-variables unless it has already been included in the list.

Parameters
