APL2Problems in the Phrasebook project

APL2 has a problem with the ∧ (logical AND) character: when code is pasted into the APL session that executes well in the other Unicode interpreters it will not run in APL2 in case the logical AND is contained, because APL2 does not recognize this character. In fact you cannot insert it into the session, but you can insert it into an edit window in APL2. The logical AND appears than as a ⎕ which stands for "char not recognized". IBM has confirmed this.

It works fine the other way round: you can copy this statement within APL2 (after correcting the logical AND) and insert it into one of the other Unicode interpreters. This is because the ASCII char is converted into the APL char when it ends up in APL code. IBM is considering to implemented the same behaviour into APL2.

Because there is nothing wrong with the statement as such it is considered to run in APL2 after fixing the ∧-problem.
