Locking a file in ksh

We want to lock a file, during a program(pgm1) execution(until the execution of the program is completed), so that other program(pgm2) can't read/edit that file, until execution of earlier program(pgm1) is completed. How can this be achieved thru shell scripting...
we tried chmod +l option, but it didn't work....

Thanks for u r suggestions in advance
