Further guess (but informed by a brief read-up in UNIX in a Nutshell):

The conditions for an 'if' statement should be enclosed in parentheses,
rather than using the [ or test.  However, it may still do funky stuff
with the command substitution...

The block syntax for "if" statements is:

if (expr) then
    cmds
endif

===========

if (expr) then
    cmds
else 
    cmds
endif

==========

if (expr) then
    cmds
else if (expr) then
    cmds2
else
    cmds3
endif

HTH,

Dan
