Report Abuse. You can use a flag in any programming language. It's just a variable to hold the state of a condition. Most are boolean (basically, on or off, 0 or 1) but can be any value. A simple flag could be, if a certain condition is true then flag = 1. Then later in the program the value of flag can be tested.eport Abuse. You can use a flag in any programming language.

The way I interpreted it, was that you can leave when you are about 25 weeks pregnant. I think you get something like 15 or 17 weeks pregnancy leave, and then 35 weeks maternity leave. If you save them up, though, you get almost a full year with baby.
If you want to change the date you start your maternity leave, you must give your employer notice of the new date at least 28 days before the new date or the old date, whichever is earliest.If there is a good reason why that it not possible, tell your employer as soon as you reasonably can.nce you have given notice, your employer must write to you within 28 days and state the date you are expected to return from maternity leave. If you are only entitled to OML this will be 26 weeks after the start of maternity leave.
