Re: [Seed7-users] Multi-Dimensional Return Bug

[Thomas M. <tho...@gm...>]

Hi Zachary

In your example the two occurrences of 'array array string' are considered as
two different types. This triggers the error. If you introduce a named type
for the two dimensional array the error vanishes:

  const type: stringArray2D is array array string;

  const func stringArray2D: test_multiplication (in string: value) is func
    result
      var stringArray2D: data is 0 times 0 times "";
    begin
      data := 3 times 2 times value;
    end func;

You are right that this happens with all types of multi-dimensional arrays.
Declaring a named type helps in all these situations.

I also added an explanation to the FAQ at
http://seed7.sourceforge.net/faq.htm#two_dimensional_array .

I hope this helps
