A common array

["Ratson Janiv" <janiv@013.net.il>]

Hi,
I need to write a program that creates a random number of tasks.
I need the tasks to update a common array (1 array for all the tasks).
do I need keep the array updating in critical section (I know that each task
will update a differnet cell in the array), if so how ?
Also I need to write a mechanism that enables the task to perform the check
twice with two differnet parameters, e.g. I call Task X to  check Numer 4 in
the array, and after it finishes, I want it to notify me, and also I want
teh task X to check the 18 Number.

for the decency, I M studying Ada, and it is part of my work, so please try
to help me as much as U can without writing the answers to me, I think some
guide lines will be helpful.

Many Many thanks,
Janiv Ratson.
