- Notes from before the conversion: Standard syntax: = if a then b Alternative syntax = ? a : b Compound clause syntax (multiple actions) "if a then x, y, z" or "if a then x; y; z"
- Ceeeb
- Any variables you declare within the body of an if/then statement (ie between the curly braces) are local to that 'if' statement, and are destroyed at the end of the statement. If you know you want to use the variable outside the 'if' statement, make sure your declare it before the 'if' statement.
