How to? The mystery of the unusable file names (file!test!.ext)

[Juppycmd]

For one reason or another, I'm creating files containing two ! like for example "file!test!.ext" ... but they're unusable with tcc, at least with the methods I've tried.

The problem is that simply using it as is ignores the !test! part, like
[c:\] echo file!test!.ext
file.ext

To do anything with it, I have to use setdos like
[c:\] setdos /x-3
[c:\] echo file!test!.ext
file!test!.ext

Obviously, this is no good when using variables like
[c:\] setdos /x-3
[c:\] set variable=file!test!.ext
[c:\] echo %variable
variable
[c:\]echo %@lines[%variable]
%@lines[%variable]
[c:\] setdos /x+3
[c:\] echo %variable
file.ext
[c:\]echo %@lines[%variable]
TCC: (Sys) The system cannot find the file specified.
"%@lines[file.ext]"
... note that the variable itself is set just fine, I can check with just typing "set variable"

My questions:
1. What is it with the two ! anyway that confuses the heck out of tcc?
2. How do I get tcc to handle these strange file names in a variable?

Thanks!

WAD - this is a CMD "feature".

To turn it off, go to "OPTION / Startup" and uncheck "CMD.EXE delayed expansion (!var!)".

Thanks, I didn't have the slightest doubt it's WAD, though it's actually more like another case of WADTNUW (works as designed though no-one understands why) :->

Thanks for the link, amazing what things you can run into if you dabble with the options and then forget about it :-p
