that allowed software to perform file locks. Locking files became necessary when MS-DOS began allowing files to be accessed simultaneously by multiple programs, either through multitasking
or networking.
There were five locking modes:
The program runs as a Terminate and Stay Resident
program and is typically loaded at boot-up.
/F:space Allocates file space (in bytes) for file-sharing information.
/L:locks Sets the number of files that can be locked at one time.

Computer multitasking
In computing, multitasking is a method where multiple tasks, also known as processes, share common processing resources such as a CPU. In the case of a computer with a single CPU, only one task is said to be running at any point in time, meaning that the CPU is actively executing instructions for...
