Actions Increment and Decrement TDLByte #24 Dear Developers, In TDLByte#23, we learnt how to access variable value at different scopes in variable framework. This TDLByte discusses about the actions Increment and Decrement in user defined function. What is it? Action Increment increases the specified variable value by 1. Similarly, action Decrement decreases the specified variable value by 1. A lot can be done in TDL using these actions. The following illustration shows how to change the variable value using the actions Increment and Decrement by specified number: Here the value of variable Counter is 9 i.e. 5+4. Here the value of variable Counter is 2 i.e. 5-3. Here the value of variable Counter is 2. Yes, this also works! Increment the value by -3, i.e. 5+ (-3) = 5-3 =2 Here the value of variable Counter is 7. How? Decrement the value by -2, i.e. 5-(-2) = 5+2 =7 Stay tuned to know more about variable framework!
