Bingo !
The syntax with or without parenthesis makes it work differently, at least
for $0 !
-> with the keyword "function myfunc1", $0 returns function name myfunc1
-> with the parenthesis "myfunc2()", $0 returns the global script name
myscript.
I previously thought that both syntaxes were totally equivalent, as said in
the O'Reilly "Learning the Ksh".
Thanks a lot.
