Starts an optional, alternative conditional assembly block.
.else statement-group
statement-group
Any valid assembly statements.
This directive must be part of an .if ... [.elseif] ... .else ... .endif conditional structure (with each of these directives starting a new line). The assembler processes the assembly statements that .else introduces only if the bool-expr condition of the .if directive is false.
If this directive is part of a conditional structure that includes several .elseif directives, the assembler processes the assembly statements that .else introduces only if all the bool-expr conditions are false.
