In [31]: int(psspy._i)
Out[31]: 2147483647


The number 2,147,483,647, is the largest 32bit signed number, but I still haven't completely figured out what PSSE does with it. For example, if I create a machine and don't specify any values I get the following defaults:

• Pmax = 9999.0
• Pmin = -9999.0

I still haven't figured it out completely, but it is a start. Right now it looks like PSSE replaces psspy._i with the default specific to a certain model/parameter.
