- NEW TOS FEATURE!
- ================
- One of the new features of Rainbow TOS is the ability to set a program
- for "fastload." This is accomplished by setting a bit in the program
- file which tells TOS that the program can be loaded without having all
- of memory cleared for it. Setting programs for fastload is most useful
- on machines like Mega 4's with a lot of memory. Clearing 4 megabytes of
- memory can take a significant amount of time - a program set for
- "fastload" can start up to a second faster. That may not sound like
- much, but when you're running a program which runs other programs (in, for
- example, a programming environment) saving a second on each program load
- can add up. And it makes your ST feel much faster when everything is
- loaded seemingly instantaneously.
-
- Wot's a fastloadbit?
- ====================
- Now, we could have told everyone which bit was the fastload bit and
- watched everyone whip out their handy sector editors and flip that bit
- in each of their programs - but we're not that sadistic. MAKEFAST is a
- program which will set the fastload bit on any program. It is one in a
- series of what I like to call "AlertWare," that is, a program which
- does everything via the simplest AES call that exists: form_alert().
- It is sort of a pain to wade through all those alert boxes, but it's
- quick and dirty to program, and it gets the job done. You do have an
- alternative with my AlertWare, though - I try to make things run from
- command lines as well as from the desktop.
-
-
- From the desktop...
- ===================
- When you run MAKEFAST from the desktop, it presents you with
- (surprise!) an alert box. The first one asks you if you want to
- Continue or Quit. If you bravely select Continue, you are then
- presented with an alert which asks you which function you want to
- perform: MakeFast (set a program's fastload bit), MakeSlow (clear a
- program's fastload bit), or Check (see if a program is set for
- fastload). Make a selection, and use the file selector which appears
- to select the program to check. Don't worry if you make a mistake and
- select a Spectrum picture instead of a program - MakeFast won't do
- anything with files that aren't executable. It will let you know if
- you selected a file which was not an executable program. Also, if you
- try to MakeFast a program which is already set for fastload (or
- MakeSlow one which is not set for fastload), MakeFast will leave the
- program alone and tell you that there was no change. After the function
- is complete, you're back to the "Continue/Quit" alert box.
-
- On a command line
- =================
- When installed as a TOS Takes Parameters application, or run from a
- command line shell, MAKEFAST can be used to manipulate more than one
- file at a time. From a command line shell, type:
-
- makefast -h
-
- to get a message describing the usage. Long after you've lost this
- doc file, you'll still be able to use makefast -h to remind you how to
- run makefast.
-
- Note that if you are using makefast as a TTP application, you don't have
- to type "makefast" at the beginning of the command line - the desktop
- fills in that part of the command for you.
-
- To set the fastload bit in file1, file2, and file3, use the command:
-
- makefast file1 file2 file3
-
- To clear the fastload bit in filea and fileb, use the -Slow option:
-
- makefast -s filea fileb
-
- To check the fastload bit in all files in a directory, use the -Check option:
-
- makefast -c *.*
-
- If any of the files are not executable, MAKEFAST will inform you of that fact.
- Note that filename wildcards will NOT be expanded if you are running makefast
- from the Desktop TTP dialog. If you are using the TTP dialog, you must
- type out all the filenames to check.
-
- Why MakeSlow?
- =============
- Fastloading works because almost all programs don't require that all of
- memory be set to zeros when they start up. What Rainbow TOS does when
- it sees a file with the fastload bit set is it only clears as much
- memory as the program needs cleared. The rest of memory is left alone.
- The operative word here, though, is "almost." Some programs insist on
- having all of memory cleared for them, among them is Microsoft Write.
- Don't try to MakeFast Microsoft Write, because it won't work correctly.
- Also, using MakeFast on desk accessories yields mixed results. BE VERY
- CAREFUL when using MakeFast to speed up desk accessory loading. If you
- run into a problem, you can always use MakeSlow to clear the offending
- program's fastload bit.
