Summary	0036090: Clarify documentation on case-else statement
Description	Reference guide, the case statement (13.2.2) The case else part works implicitly as a block, accepting multiple command statements, which is by design. The documentation should be clearer on this. It says: "The case statements can be compound statements (i.e. a Begin..End block)." To this could be added: "The else part can contain multiple statements even without a Begin..End block." Additionally, under the section "The following are valid case statements", one of the examples should include a two-line else statement to show it is possible.
Tags	No tags attached.

Marco van de Voort 2019-09-19 22:49 manager ~0118123	The else part CAN'T contain multiple statements without begin..end. A counterexample would be necessary. Note that if you need multiple else statements, you are probably of the track. Search for dangling else.

Michael Van Canneyt 2019-09-19 23:23 administrator ~0118125	@marco, of course the else part can contain multiple statements: begin case random(10) of 1 : writeln(1); else Writeln('a'); Writeln('b'); Writeln('ahah'); end; end. compiles and runs fine. You can't have multiple else clauses of course.

Michael Van Canneyt 2019-09-19 23:34 administrator ~0118126	Well, the syntax diagram clearly mentions 'statement list' in the else clause. But I added an example, and made it more explicit.
