Description

Some examples in documentation Procedures.pdf do not work :

This one works

HELLO["aa"]

Procedure HELLO[a$]
  Print "Hello, I am a procedure ! " + a$
End Proc

But this one, with a return value, does not :

Print HELLO["one"]

Procedure HELLO[a$]
  Print a$
End Proc[a$+a$]

main.aoz:1:12: error: Syntax error

That's because it's bad code. Should be:-
HELLO["one"]
Print Param$
Procedure HELLO[a$]
Print a$
End Proc[a$+a$]

Problem still exists in 0.9.6.

No, it's not bad code. According to the AOZ documentation, The example Baptiste gave should work.
See the Procedures.pdf (attached) for details. Search for the heading " Returning values from a procedure ".

NOTE: The old method using Param, Param$, Param#, etc. is still supported as well.
