I found a problem with some packages at riscos.info. I use the
Vorbis-Tools for my little application OggTag. It looks that a lot of
the command line programms at riscos.info has this problem.
In Vorbis-Tools !Boot is the command
Set Alias$vorbiscomment WimpSlot -min 686k |M Run
<Vorbis-Tools$Dir>.vorbiscomment %%*0
In !Run of OggTag I wanted to check for vorbiscomment with
If "<Alias$vorbiscomment>" = "" Then Error OggTag requires the
Vorbis-Tools
With this command I get "String not recognised". The reason is the "|M"
in the Set Alias$... command of Vorbis-Tools. With the help of Thomas
Milius I found a way round the problem:
Unset vorbiscommentCmdLen
X SetEval vorbiscommentCmdLen LEN(Alias$vorbiscomment)
If "<vorbiscommentCmdLen>" = 0 Then Error OggTag requires Vorbis-Tools
Unset vorbiscommentCmdLen
But I think a better way is to change
Set Alias$vorbiscomment WimpSlot -min 686k |M Run
<Vorbis-Tools$Dir>.vorbiscomment %%*0
in Vorbis-Tools !Boot to
SetMacro Alias$vorbiscomment Set WimpSlot -min 686k |M Run
<Vorbis-Tools$Dir>.vorbiscomment %%*0
In !Boot are similar commands for the other Vorbis tools.
I hope you understand the Problem. If you have installed the
Vorbis-Tools try
If "<Alias$vorbiscomment>" = "" Then Error OggTag requires Vorbis-Tools
in a Taskwindow or if you have installed Curl
If "<Alias$curl>" = "" Then Error See the error
or GZip
If "<Alias$gzip>" = "" Then Error See the error
...
With Whois there is no problem with
If "<Alias$whois>" = "" Then Error See the problem
because there is no WimpSlot in the alias. But I think to set the
WimpSlot is a good idea.
