token

How to handle the case where the token 'for' is used in two different situations in the language to parse? Such as statement and as a "parameter" as the following example:

echo for print example
for i in {0..10..2}
  do
     echo "Welcome $i times"
 done

Output:

for print example
Welcome 0 times
Welcome 2 times
Welcome 4 times
Welcome 6 times
Welcome 8 times
Welcome 10 times

Thanks.
