Hi support team,

Perforce uses to replace a hash sign (#)&nbsp;by %23

Obviously FB&nbsp;expects a variable starting at the percent sign and fails to iterate the following list:

File No.50.txt  
File #50.txt  
File %2350.txt&nbsp; \<--- forces the iterator to fail

&nbsp;

If I&nbsp;double the percent sign the iterator does nothing.

A sample project is attached.

Best regards

Michael

You can disable recursive variable expansion by using ! in front of the variable name, e.g %!list%

Hi Vincent,

that's quite a fast response :-) Thank you.

But, I am not quite sure how to use your answer. My problem is:

- I&nbsp;have a File with the name "File #1.txt"

- perforce cannot handle this because the # sign indicates the revision number, therefore in case I&nbsp;ask for a list of files I&nbsp;get "File %231.txt"

- if one single in the 'list of lines'&nbsp;of the 'list iterator'&nbsp;contains this file name, the iterator fails

Where I&nbsp;have to apply the exclamation mark you mentioned?&nbsp;I cannot change the filename to&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; File %!231.txt&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; because this file does not exist - Perforce will not find such a file.

Best regards

Michael

Hi Michael  
  
The ! symbol addresses the issue you reported, I have modified the example project and it works correctly. You should be able double quote the filename when passing it to perforce. Otherwise I guess I'm not seeing what the problem is. Perhaps if you flesh out your example a bit more so I&nbsp;can see exactly what you are trying to do?

Hi Vincent,

thank your for the modified sample. Now I see WHERE&nbsp;you applied the exclamation mark... This works fine.

Thanks a lot again.

Michael
