Yes, but it's a little tricky because Cobol uses different terminology
than modern languages. Cobol's equivalent of functions or subroutines
are called "subprograms". Variables declared in the local-storage
section of the data division are dynamically allocated and initialized
each time the subprogram is run, much like local variables in
functions are.
