!ProFiler/Dox/SysVars
This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

<html><head><title>ProFiler system variables</title></head> <body> <h1><center><u>ProFiler system variables</u></center></h1> There are several system variables in use. Some of them are documented elsewhere, the rest of them below. <h2>Filer$Selected</h2> This variable contains the first selected file in the current viewer. The 'current viewer' in this context is the latest one with the input focus. If no such file can be determined, the variable contains "null:". Setting this variable to a filename causes the file to be selected if a viewer is showing it. This variable is most useful when defining custom filer keys. For example:<br> <kbd>SetMacro Filer$Key_1DD IconSprites <Filer$Selected></kbd><br> �will cause Shift-Insert to load the selected file into the wimp sprite pool. <h2>Filer$Viewer</h2> This variable contains the name of the current viewer. If there is no current viewer, the variable contains "null:". This variable can be used for the same kind of things as Filer$Selected. I also use it as an easy way of outputting files from simple Basic programs. <h2>Filer$Key_xxx</h2> When a key is pressed in a filer viewer, the configured action is taken. If there is no configured action, the variable <code>Filer$Key_kkk</code> is checked. If it exists, the contents of it is executed as a task. If not, the key is passed on to the remaining applications. See Filer$Selected above for an example key definition. <h2>File$Type_xxx</h2> <h2>Dir$Type_xxxx</h2> See <a href="./ExtTypes">ExtTypes</a>. <h2>Alias$@BootDir_xxxx</h2> <h2>Alias$@RunDir_xxxx</h2> <h2>Alias$@RunType_xxx</h2> See <a href="./RunAndBoot">Running and booting</a>. </body></html>
