If statement - tcsh
 

I need to loop through a bunch of different scenarios (variable scen), but can't figure out how to use the if statements in the tcsh shell script. Getting the error "if: Expression Syntax" Can someone please tell me what I have wrong? Simplified code follows! Thanks!

#!/bin/tcsh -f
#
set val = 0

foreach scen ( a b )

echo $scen

if ($scen==a) then
echo $scen
else
echo $val
endif

end

The if statement needs spaces,
e.g.
if($scen == a) then
