The state of the carry flag and the value held in the D register are now manipulated so as to give the appropriate value for the 'error register'.

THE 'DE,(DE+1)' SUBROUTINE
This subroutine performs the construction - LD DE,(DE+1) - and returns HL pointing
to'DE+2'.

2AEE 	DE,(DE+1) 	EX 	DE,HL 	Use HL for the construction.
		INC 	HL 	Point to 'DE+1'.
		LD 	E,(HL) 	In effect - LD E,(DE+1).
		INC 	HL 	Point to 'DE+2'.
		LD 	D,(HL) 	In effect - LD D,(DE+2).
		RET 		Finished.

THE 'GET-HL*DE' SUBROUTINE
Unless syntax is being checked this subroutine calls 'HL=HL*DE' which performs the implied construction.
Overflow of the 16 bits available in the HL register pair gives the report 'out of memory'. This is not exactly the true situation but it implies that the memory is not large enough for the task envisaged by the programmer.

2AF4 	GET-HL*DE 	CALL 	2530,SYNTAX-Z 	Return directly if syntax is
		RET 	Z 	being checked.
		CALL 	30A9,HL=HL*DE 	Perform the multiplication.
		JP 	C,1F15,REPORT-4 	Report 'Out of memory'.
		RET 		Finished.

THE 'LET' COMMAND ROUTINE
This is the actual assignment routine for the LET, READ and INPUT commands.
When the destination variable is a 'newly declared variable' then DEST will point to the first letter of the variable's name as it occurs in the BASIC line. Bit 1 of FLAGX will be set.
However if the destination variable 'exists already' then bit 1 of FLAGX will be reset and DEST will point for a numeric variable to the location before the five bytes of the
