- SWELL is a powerful TSR (terminate-stay-resident) utility for users
- who need to shell from one programme to another and find themselves
- short of Random Access Memory.
-
- SWELL allows you to SHELL infinitely from one programme to another
- and then back again through the conventional EXIT command. Without
- SWELL you must hold the parent programme in RAM when you SHELL to
- the next level. This means you will inevitably run out of memory if
- you continue to SHELL from the PARENT to the CHILD to the GRANDCHILD
- to the GREATGRANDCHILD and so. However, with SWELL the memory
- requirements of each PARENT are swapped off to the disk of your
- choice as you SHELL through the generations INFINITELY!
-
- As you begin to EXIT back up the generation tree, SWELL will reload
- each successive parent programme back into RAM.
-
- In addition to user-invoked SHELLS, SWELL works equally well with
- any programme that calls separate routines without your knowledge.
- For those of you working with compilers, you know how much memory
- you can need! Well SWELL makes the problem go away painlessly by
- swapping off memory.
-
- Since SWELL swaps RAM memory to disk, you may wish to have SWELL
- swap memory requirements to a RAM disk to increase the speed.
- Generally you should allow around 512 K of free space in the RAM
- disk you have SWELL swap memory to. However, THERE IS NO LIMIT to
- the amount of memory SWELL can swap off. It is limited only by the
- available space on disk (real or virtual).
-
- There are some cautionary notes to consider when using SWELL. Any
- TSR loaded after SWELL will be declared a "non-event". This means
- that you should load SWELL last (particularly if you are going to
- use SWELL in your autoexec.bat file).
-
- For ordering information, or a more technical explanation of
- SWELL.EXE, read the SWELL.DOC file.
