Question

can we use logical operators in a decision box in flowchart?.. example: usr_Name="abc" && psw="123" assume above condition in a one decision box in flowchart thanks..

Yes we can use logical operators in a decision box for more details refer this tutorial Decision icons allow you to test a condition and redirect the flow according to the outcome. Icons can be placed in either branch from the decision icon. Display Name The name of the icon that appears on the flowchart. Condition The decision box tests this condition to see which branch to continue down. If the condition evaluates to 0 or false then the 'No' branch is chosen. If the condition evaluates to a non zero number or true then the 'Yes' branch is chosen. Conditions can be made up from numbers, variables and operators: See Calculation Icon Properties for a list of valid operators. Numeric values can be in decimal (unmarked) or in HEX format (preceded by 0x) or in Binary format (preceded by 0b) e.g. 255 or 0xFF or 0b01010101. Assuming that the variables have been previously defined, all the following are valid conditions. DELAY = DELAY + 1 DELAY = (MYVAR + 3) * 3 NEXTBIT = LASTBIT >> 2 & MASK AANDB = PORT_A AND PORT_B INVX = NOT X To test for two or more conditions, write tests for the individual conditions and combine them with logical operators. When both conditions must be true: condition1 && condition2 When one condition being true suffices: condition1 || condition2 Assuming that the variables have been previously defined, all the following are valid conditions. (DELAY = 1) && (X = 0) (DELAY = 1) || (DELAY = 4) (DELAY = 1) || ( (DELAY = 3) && (X = 0) ) Variables Arrow Clicking on the down arrow brings up the variables dialog window allowing you to select an existing variable or to create a new one. Swap Yes and No Normally the 'Yes' path of execution goes off to the right of the decision icon and the 'No' path carries on down the flowchart. Select this option to swap the two branches around.
