Illegal modification of .ENDR directive keyword by lexical
 operation.

    Error: While your repeat range contains a .ENDR directive that
    ends the repeat block, the .ENDR directive is modified by a
    lexical operator so that it can no longer be recognized as a
    .ENDR directive keyword after lexical processing.

    User Action: Change the statement to avoid modifying the .ENDR
    directive keyword with lexical operator processing. See Chapter
    3 in the Reference Manual for information about using lexical
    operators.
