Concatenation
TSL denotes the string concatenation operator by “..” (two dots). If any of its operands is a number,
TSL converts that number to a string:
print( " Hello " .. " World " )
print(0 .. 1)
Output of code above:
Hello World
01
Branching
TSL uses the “if” keyword to do conditional branching.
--
-------------------------------- IF blocks ------------------------
--
-- Zero IS true! This is a contrast to C where 0 evaluates false. In TSL,
--
both
"
nil
"
and false are false and everything else is true.
if 0 then
print("Zero is true!")
else
print("Zero is false.
"
)
end
