Starts a conditional assembly block, making assembly conditional on the inequality of two strings.
.ifnc string1, string2 statement-group
string1
Any valid string.
string2
Any valid string.
statement-group
Any valid assembly statements.
If string1 and string2 are not equal, the assembler processes the statements of the block. (The inequality comparison is case-sensitive.) If the strings are equal, the assembler skips the statements of the block.
Each .ifnc directive must have a matching .endif directive.
