BITOR var1,var2
This statement do a bitwise OR between var1 and var2; that is, every corresponding bit of the variables (from left to right) is logically added and result is overlayed in var1.Logically added mean: 1 x 1 = 1; 1 x 0 = 1; 0 x 1 = 1; 0 x 0 = 0.This bitwise OR is ever done no matter of what type of variables are used and its length correspond to the shortest length between var1 and var2.
Parameter Name Mode Type coding Remark 1 var1 Input/Output Every type Max length 255 char. 2 var2 Input Every type Max length 255 char.
