Taron	Posted - 04/09/2014 : 11:33:43 AM Origin Ver. 8.6 b70 Operating System: Windows 7 x64 Hi, I need help with a little problem I have concerning a Labtalk script. I want to define a range variable depending on a certain condition. I tried to do this with the following if clause: if(directioninc < 0) { range rr1a1 = [%H]1!Col(1); type "variable < 0"; } else { range rr1a2 = [%H]1!Col(1); type "variable > 0"; }; range rr1b = [%H]1!Col(2); rr1b = rr1a1; I do not know why, but for some reason this construct does not work. Everytime I get the error: Undefined variable: rr1a1 The strange thing is that the if construct seems to work because the "variable > 0" or "variable < 0" is printed every time but somehow the ranges do not get defined, which is the main idea of this part of my script. Can anyone help me and solve why this does not work?

lkb0221	Posted - 04/09/2014 : 3:17:57 PM Hi, This is because the range variable is defined inside the if condition, so Origin consider it as a local variable and thus be deleted once the if section ends. You can use @global to force the variable be a global variable. For example: // if(directioninc < 0) { @global=1; range rr1a1 = [%H]1!Col(1); @global=0; // turn it off when done define type "variable < 0"; } else ... // Zheng OriginLab
