[Gambas-user] Returning multiple values from a function

[Rolf-Werner Eilert]

This is just the way I do it. But when I have more than 2 values to 
separate, I'll use another string[] to have them splitted (though I like 
to use a Tab (chr$(9)). This runs incredibly fast in Gambas.

Let's assume you receive a string like "10|cat|male|black" I would do

dim partstring as new string[]

partstring = split(sResult, "|")

'and now you can examine the part-strings:

if val(partstring[0]) = 10 then...

if partstring[1] = "cat" then...
