I found this on the forum today. Why might declaring a global string with a " : " be useful. I understand how the colon works but I don't see how this can be applied.

Thank you.

It was to allow strings of text to be easily manipulated. For example...

MyHour$ + cSEP + MyMinute$ + cSEP + MySecond$

would produce "10:23:46", for example. But the user could change the value of cSEP to "-", in order to set the disply format of the time to their preferences.

right, say you had ":" as a literal throughout your code, then, like Batty says, you wanted to change it to "-", you'd have to troll thru all of the code and change it manually. No big deal if its only there 5 times say. What if its there 100 times, or a 1000?
Using and alias like above or even a constant solves that problem, you can simply change the ONE definition of cSep and it will be reflected throughout the code.

Its 9/11 - but its FAKE 9/11 Ts=SQRT(Df/16)
