RE: Swap array values? In UV
Within BASIC, try array(x)=BITXOR(array(x),array(y)); array(y)=BITXOR(array(y),array(x)); array(x)=BITXOR(array(x),array(y)); It only works with integers. Other real numbers and strings won't work. -- u2-users mailing list [EMAIL PROTECTED] http://www.oliver.com/mailman/listinfo/u2-users

RE: Swap array values? In UV
UniVerse 10.0.x and higher have the SWAP command in BASIC. Please refer to our documentation regarding its use. -- original message -- Is there a command to swap two array contents? Like matswap array(x,y) will swap the contents of array(x) - array(y) and array(y) - array(x) Without using a temp varible. Yes I know I can do it that way.

RE: Swap array values? In UV
Sorry Leroy, but swap only swaps non array values, and the mat portion will swap one array with another array I want to swap two values inside an array. I tried swap a(1),a(2) but it did nothing tried. dim a(10) a(1)=5 a(2)=6 print a(1),a(2) swap a(1),a(2) print a(1),a(2) and got: 5 6 5 6 but it did compile.

RE: Swap array values? In UV
I miss understood you. No, UV doesn't provide the facility to do that within an array of any type- dynamic or dimensioned- that is not its purpose. It will work if the arrays are different, such as: DIM A(10),B(10) MAT A = '' MAT B = '' A(1) = 678 B(1) = 234 CRT 'BEFORE:' CRT 'A(1) = ':A(1), 'B(1) = ':B(1) SWAP A(1),B(1) CRT 'AFTER:' CRT 'A(1) = ':A(1), 'B(1) = ':B(1) C = '' D = '' C1 = 1234 C2 = 334 D1 = 5678 D2 = 778 CRT 'BEFORE:' CRT 'C1 = ':C1, 'C2 = ':C2 CRT 'D1 = ':D1, 'D2 = ':D2 SWAP D, C CRT 'AFTER:' CRT 'C1 = ':C1, 'C2 = ':C2 CRT 'D1 = ':D1, 'D2 = ':D2 BEFORE: A(1) = 678 B(1) = 234 AFTER: A(1) = 234 B(1) = 678 BEFORE: C1 = 1234 C2 = 334 D1 = 5678 D2 = 778 AFTER: C1 = 5678 C2 = 778 D1 = 1234 D2 = 334 Since a variable can be considered a dynamic array with a only a single attribute (our docs show a variable and not a dynamic array), I used a dynamic array to illustrate the entire array gets swapped with another array.

Re: Swap array values? In UV
Glen, XOR means Exlusive OR. Example: 00110 BITXOR 10011 yields 10101 because 0 XOR 1 = 1, 0 XOR 0 = 0, 1 XOR 0 = 1, (here's the tricky one) 1 XOR 1 = 0 (because it needs to be exclusive), and 0 XOR 1 = 1 10 1 0 1 The example is still hard to read, even when you understand XOR, because it is a counter-intuitive approach. It is, however, frighteningly clever. - Charles 'Exclusive' Barouch Glenn W.
