I added new keyword to moderate while - else (otherwise)
new codes is

while( I>5 ) do begin Dec(I); write(I); end otherwise write(' otherwise
while ');

if (I<10) then while( I>5 ) do begin Dec(I); write(I); end otherwise
write(' otherwise while ') else write(' IF ELSE ');

I need  help to implement it
I added more info needed by compiler ,but I don't know what is
executionweight in pass_generate_code function of tcgwhilerepeatnode class
I check other classes and functions ;like (if,for,exit) node
pass_generate_code ,but I can't find relation between executionweight and

please define it for me!

Thanks a lot.
