You can store more of 16MB into a variable,
but you cannot do some simple operations only:
-readonly : LEN(),UPPER(),LOWER(),$,AT(),compare,LIKE(),SUBSTR()...
-direct copy ("=" or STORE )

But some operations STRTRAN(),CHRTRAN()...
they are written for short strings and they are not optimized regarding the cache, therefore the time of elaboration explodes.

The process's memory have the OS's 2GB upper bound.
