how do i add 1 to the 1..3 par to make it 1..4

code:

var stuff : flexible array 1 .. 3, 1 .. 6 of string

***new stuff, upper (stuff) + 1,***
   


the part that doesn't work is ***

I don't believe Turing will allow for the complex multi-dimensional array reallocation as of yet. Can someone verify this?

Maybe I misunderstand...
code:
var stuff : flexible array 1 .. 3, 1 .. 6 of string

put "initialize elements"
for i : 1 .. upper (stuff)
    stuff (i, 1) := "checking " + intstr (i)
end for

put "outputting elements"
for i : 1 .. upper (stuff)
    put stuff (i, 1)
end for

put "new element"
new stuff, upper (stuff) + 1, 6
stuff (upper (stuff), 1) := "new 4"

put "outputting elements"
for i : 1 .. upper (stuff)
    put stuff (i, 1)
end for


A two dimensional array is just an array in which each element is another array. Changing the dimensions means adding another array to the end, or taking one off. Unless you are trying to change the size of the second arrays (that is, the ones inside the main array) in which case you Mr. Glib is right.
