Hm, i did not receive Bakul's mail. Well i did not use it long
enough. I think this came up in the past already, it could have
been it was a mutilated version, there definetely was no goto in
this DOS-looking UI with menu bar, with menu entries for
compilation plus, help screen etc etc. Borland Pascal, Borland
dBASE it must have been then. Didn't i say "maybe the teacher had
an option to turn it on" or something :) Yeah, i do not know, but
there was no goto, definetely.
|Pascal also had to go. (Thanks...I'm here all week.)
Ah, and all the many-page program listings in Delphi, what a waste
of paper. Whether anyone really typed them out, not me.

Terrible just as pthread_cleanup_push/pop, and that can be
entirely local-to-scope. Terrible even if there would be
"closure"s that could be used as arguments instead of a function
pointer. gcc supports/ed computed goto's, which would also be
nice in that respect. And some kind of ISO _Xy() which could be
used in conditionals dependent on whether the argument is
a computed goto, a "closure" or a function pointer (or a member
function pointer).
I always hated that C++ is not ISO C plus extensions, so your
"C/C++" is not true for a long time...
