Instruction Description

ASC

STRING SEARCH

Source ST38:40

Index35

Search ST52:80

Result42

ASCII String Search	If input conditions are true, search ST52:80 starting at the
ASC	35th character, for the string found in ST38:40. In this
	example, the string was found at index 42. If the string is
	not found, the ASCII instruction minor fault bit S:17/8 is set
	and the result is zero.

ASR

ASCII STRING COMPARE

Source A	ST37:42
Source B	ST38:90

ASCII String Compare	If the string in ST37:42 is identical to the string in ST38:90,
ASR	the instruction is true. Note that this is an input instruction.
	An invalid string length causes the ASCII instruction error
	minor fault bit S:17/8 to be set, and the instruction is false.
