S-Register Commands

The following five commands apply to S-Registers, which are described further below.

ATSn=v	S-Register n to Value v. Sets S-Register n to the value v.

ATSn	Establishes S-Register n as the Selected Register. Sets S-Register n as the last
	register accessed, where n is the number identifying the S-Register. For example,
	ATS7 establishes S7 as the last accessed register.

ATSn?	Reports the Value of S-Register n. Reports the last value stored into S-Register n. If
	n is omitted, the last S-Register is accessed.

AT=n	Last Accessed S-Register to Value v. Use this command to set the last accessed
	S-Register to the new value n.

AT?	View Last Accessed S-Register. Displays the contents of the “selected” S-Register.
	The “selected” S-Register is the last S-Register that was accessed using an S-Register
	command, or selected with the ATSn command.
