Line 1,296:
There is no explicit memory allocation in the REXX language, variables are allocated as they are assigned (or re-assigned).
<br>Most REXX interpreters will obtain a chunk (block) of free storage, and then allocate storage out of that pool if possible, if not, obtain more storage.
<br>One particular implementation of REXX has predefined and limited amount of free storage.

There is no explicit way to de-allocate memory, but there is a DROP statement that "un-defines" a REXX variable and it's memory is then free to be used for other variables, provided that free memory isn't too fragmented.
