  Hi Steven

It depends which operating system you use.
I worked with an Meridian Ada-compiler under DOS and I was able to use an
task entry as an interrupt handler - it worked even perfectly.
But under other operating systems the 'for ... use ...' statement is
interpreted in an other way. Under Unix your entry is not connected to an
interrupt but to an Unix-signal.
