Thats slang for the #!/bin/bash or #!/bin/python, #!/path/to/whatever
as the first line of the file.  Its the interpreter that the script is 
intended to be executed by.

I must confess I am not familiar with the requirements of a ".scm' file, 
so my advice is to be seasoned as needed. :)

Compare the first line on the file that works, with the first line of the 
one that does not. I believe its case sensitive.  If you post both lines 
as a straight copy/paste, perhaps someone with better knowledge that I 
can illuminate the problem.


I do not know what you mean by "other masks disappear".
