Question: #89 of #131

Section: DataWindow

Version: 5.0 or later

Question

Can you declare CONSTANTS in PowerBuilder?

Click here to see the answer

From version 5.0 onwards, you can declare constants in POWERBUILDER. For example: CONSTANT APPEND_TO_ROWS 2. When you want to append to the existing rows in the DataWindow when you retrieve next time, write 'return APPEND_TO_ROWS' instead of 'return 2'. Using constants you can make the code more readable and also more efficient (in some places).
