what is quasi-reentrant program?

Answer Posted / bramar

before explaining reentrant programe let us consider an
interactive programe which will take input form user and
which will process the inputs and gives the output

in this interactive process control wil wait for user input
for a long time which means CPU will be idle

To avoid this senorio re entrant programes are designed
It will throw the map to user console and control will not
wait for user inputs and it will process other jobs
and when user give the input and he press the attention key
againg programe will be invoked with the user inputs and
the programe processes the input and it will show the
result on the console and then control will agian goes back
to some other jobs utill it got any input from the user
