I assume you mean the CSH construct equivalent to SH/KSH "for var in list do".

Here is the syntax:

foreach varname ( list )
	command $varname
	...
end

Here is an example:

foreach file ( *.c )
	mv $file $file.orig
end

Main differences from sh/ksh:  parentheses around list, no "do/done", 
terminate with "end".

Bugs:  I've worked with versions of csh where the parentheses needed to 
be surrounded by whitespace -- i.e. it has to be " ( *.c ) " rather than
"(*.c)".
