  Arrays of functions disallowed? (Message 1 to 5 of 5)

I tried to produce an array of functions with beta 13 and was told I was
redefining a function.

A short test code that gives the same error is

#declare fn_LT = array[2]
#declare fn_LT[0] = function { 1 }
#declare fn_LT[1] = function { 1 }

The third line produces the error message 'Parse Error: Redeclaring
functions is not allowed - #undef the function first!'

I believe this worked with beta 12.

System: 1GHz Athlon, 256MB, NT4 sp6, 3.5.beta.13.icl.win32

Bye for now.

Yes, it did because it was a bug:

The bug reported in the above thread concerns redeclaring the same
(function) identifier. I am trying to assign (functions) to different
array entries. I may be wrong but I don't believe this is the same thing
...

Bye for now,

You are right.  The error message appears once the first function has been
assigned to the array.  This will be fixed in the next beta.
