you seem tdo use a variant of csh on UNIX, perhaps `tcsh'.
On cygwin, you probably use another shell, probably the default: `bash'.

(Shell is the program which interprets your commands and executes them, like
command.com on DOS.)

You either have to execute tcsh on Cygwin, or you should change the commands.
In Bourne-derived shells, including `bash', you assign variables this way:

abc="a b c"

(no spaces, no `set' keyword).  If you want to learn more about shell scripting,
try any good Unix book, or Advanced Bash Scripting Guide,
