Here is a sample of a typical List-File that plays some audio modules
in random order.

Please pay attention that RandomE is a generic program launcher that can
execute any line of text that is executable in an AmigaDOS Shell window.
Therefor, it is possible to set the volume for each song in the following
examples:

; RandomE List-File
; RandomE plays the following audio files randomly

; Soft songs
C:Players/MyPlayer Volume=54 Tunes:Soft/soft1.song
C:Players/MyPlayer Volume=84 Tunes:Soft/soft2.song

; Rock songs
C:Players/MyPlayer Volume=44 Tunes:Rock/Rock1.song
C:Players/MyPlayer Volume=64 Tunes:Rock/Rock2.song
C:Players/MyPlayer Volume=54 Tunes:Rock/Rock3.song

; Classical songs
C:Players/MyPlayer Volume=100 Tunes:Classical/Classical1.song
C:Players/MyPlayer Volume=112 Tunes:Classical/Classical2.song


With the above list file you could play all your soft, rock, and
classical songs randomly, or you could play just the soft songs
like this:

RandomE Songs.list UsePattern=#?soft#?

You could play all but the rock songs like this:

RandomE Songs.list UsePattern=~#?rock#?  

And you could play just the soft and the classical songs like this:
RandomE Songs.list UsePattern=(#?soft#?|#?Classical#?)

-------------------------------------------------------------------------

What else can you do with RandomE?  How about having random Workbench
backdrops that are tiled or centered if the WBPattern prefs program
of your IPrefs replacement program supports the option?

List-File #1:  S:Backdrops_Centered.list

; Centered Patterns
C:Copy Work:Patterns/BigPic1 Work:Patterns/Backdrop
C:Copy Work:Patterns/BigPic2 Work:Patterns/Backdrop
C:Copy Work:Patterns/BigPic3 Work:Patterns/Backdrop


List-File #2:  S:Backdrops_Tiled.list

; Tiled Patterns
C:Copy Work:Patterns/Pat1 Work:Patterns/Backdrop
C:Copy Work:Patterns/Pat2 Work:Patterns/Backdrop
C:Copy Work:Patterns/Pat3 Work:Patterns/Backdrop


List-File #3:  S:Backdrop_Select.list

; Pick 'Centered' or 'Tiled'
Execute S:Backdrop_Centered.bat
Execute S:Backdrop_Tiled.bat


Batch File #1:  S:Backdrop_Centered.bat

C:Copy Work:Patterns/WBPattern_Centered.prefs ENV:Sys/WBPattern.prefs
C:RandomE S:Backdrops_Centered.list Times=1


Batch File #2:  S:Backdrop_Tiled.bat

C:Copy Work:Patterns/WBPattern_Tiled.prefs ENV:Sys/WBPattern.prefs
C:RandomE S:Backdrops_Tiled.list Times=1


Now place the following line in your startup-sequence:

RandomE S:Backdrop_Select.list

This will radomly execute one of the script files, centered or tiled,
which will then execute RandomE again to select one backdrop.  The
example assumes you have WBPattern pointing to Work:Patterns/Backdrop.

Instant random backdrops that can be tiled or centered depending on
the picture file.
