You cannot specify .ELSE in the same .IF block with either .IF_FALSE
 (.IFF), .IF_TRUE (.IFT), or .IF_TRUE_FALSE (.IFTF).

    Error: The assembler encountered an .ELSE directive within the
    same .IF block as an .IF_FALSE, .IF_TRUE, or .IF_FALSE directive.

    User Action: Check your source code and remove either the .ELSE
    directive or the .IF_x directive.
