Re: [Bug-apl] defn error with ⍝

[enztec]

no don't change anything 

i was just use to    'terminating' a function/program/procedure early' in fpc 
pascal   by   putting an    'end.'   where i wanted and the compiler would only 
see the first 'end'. and 'end' the code at that point and then by commenting 
the first 'end.' the compiler would 'see' the rest of the code.
