for loop syntax error

Postby nupogodi » Thu Jan 04, 2018 6:15 am

An empty list yields "Syntax error in control statement" but it's actually a valid statement

Code: Select all

%mylist = "A B C"    'this is ok
%mylist = " "       'this should also be valid

for %s {%mylist}
   %t = %s
next

Apparently it's valid in any other programming language in the world. In case of Python for example:

for c in "":
print c
