Interesting question, this one. I solved it by using curses linked into the
Pascal. Even then, it appears that the timeout supplied by curses for parsing
escape sequences (1 second) is way too short and I had to end up parsing
them myself (sometimes curses WOULD parse it correctly and other times it
would return the full escape sequence back). I assume intelligent folks out
there already know how to link (and use !) the curses library into HP
Pascal...it's not for the faint-hearted (and the LINES and COLS external
integers are extremely difficult to read - I've ended up with C 'glue'
routines hich are also linked in).

In actual fact, I've written my own USENET News reader using curses in HP
Pascal - am I the only one who hates rn ??

On a different note, why doesn't HP Pascal have any bitwise operators between
integers such as AND, OR and XOR ?? Or have I missed something here ?
