adding and subtracting time

[James Flanagan]

I am trying to identify the most elegant way to add and subtract time with user input in filepro.  The first example, where dummy ti is a 2 digit .0 variable, does not work properly.  The second example, by changing ti to an 8 digit hms variable does.  however, i do not want to have end users accidentally or otherwise screwing up the 00:00:00 sequence.  therefore, how can i prompt a user for a 2 digit number and ultimately get filepro to remove the respective number of minutes from my tm dummy variable.  Thank you very much in advance.


::ti(2,.0):
::input popup ti "Please enter how many minutes ago to start the downtime clock^A":
::tm=@tm-"00^A"{ti{"^A00":


::ti(8,hms):
::input popup ti "Please enter how many minutes ago to start the downtime clock^A" default "00^A00^A00":
::tm=@tm-ti:
