Create If-Else(decision making) in S-Programming Language

[Sanatdey]

This is the 1st heard level issue.
Like we can do the if else in this , it should be like
if - a == 0 - showme ~ "you_win" - showme ~ "you_loose" .
HERE

1. if and - Operator
2.a == 0 Condition For If
3.showme ~ "you_win" and 'showme ~ "you_loose" . ` is the task if the condition is true or false respectively.
