Inverted syntax: Difference between revisions

=={{header|RPL}}==

Assigning values to variables using <code>→</code> or <code>STO</code> commands presents an inverted syntax in RPL. It's also possible to invert syntax for conditional expressions, by pushing the action in the stack as a lambda expression before doing the test, but this isn't idiomatic.

≪ 1 → raining <span style="color:grey">@ Set raining to true</span>

≪ ≪ NEEDUMBRELLA ≫

'''IF''' raining '''THEN''' EVAL '''ELSE''' DROP '''END''' <span style="color:grey">@ Execute above action if true, else pop it from stack</span>

≫ ≫ '<span style="color:blue">TASK</span>' STO <span style="color:grey">@ Store above program in TASK variable</span>
