Memory leaks? What memory leaks? I don't know how to create a RPG
program with a memory leak. I figure someone like Joe P or Elvis B
could, but I suspect they would have to work at it.
Of course you do. Whenever you use ALLOC or %ALLOC in RPG you are
creating the potential for a memory leak. If you neglect to call
DEALLOC or %DEALLOC you've created a memory leak.
What saves RPG (and other languages with support for fixed-length
variables) is simply better compiler support for managing common data
types thus reducing the need for a programmer to manage storage. That
is, it is very uncommon for RPG applications to use ALLOC and DEALLOC
but it is very common for C and derivative languages to use their
equivalents. Increase the use and you increase the likely-hood of leaks.
