i create a script like this:

set oplist = `execute(“opls -d sphere*”)`
if ($oplist) then
echo ok
else
echo Sorry, object not found.
endif

but i got error: invalid if syntax, i checked that this happened probably because the $oplist has an array-like value. I mean , it works if the $oplist contain single numeric value or string etc.
anyone know how to fix it?
the goal with that ‘if’ is to check if the opls command return any value or not(null)

Yeah, this could expand to something like:

if (geo1 geo2 geo3) then

which is pretty non-sensical. Instead, try:

if (“$oplist” != “”) then


Another approach for these kinds of things is:

if (`argc(execute(“opls -d sphere*”))` > 0) then


This will run if the number of words (ops, in your case) is greater than zero.
