| The code
$ansStr1 = EV2(" \( $LBRACE 1,2,3 $RBRACE \) ");
.
.
@answers = ($ansStr1, ..
.
.
TEXT(
.
&OL(@answers[@slice]);
);
displays and behaves correctly, but the hard copy yields an error:
item[A.] ( 3 )
The braces and the rest of the set are suppressed. This is consistent behavior with similar problems.
Also, the same setup with "x : x \le 5" in place of the "1,2,3" behaves correctly but yields the hard copy error:
