Can someone please explain to me why this occurs:

I know that you can open the command prompt from within the maple interface, but how do i append instructions for it to execute a .ps1 script please thank you in advance 

Can i use the file tools package to change the file extension of a file or open up a powershell terminal to do so from within the maple interface via command line?

So, basically i plan to define procedures based on if conditions that will assume arbitarily large float approximations as being infinity, as with the example i have uploaded, but i feel that i need some people from here that are smarter than me to tell me why this is going to be terrible or what i need to consider. 

I am willing to consider my current view naive and or inept, however i feel as if computer algebra systems will eventually develop means of reducing the need for floating point results by making concise implicit steps of manipulation on floating point computations, naturally i feel as if these routines are evidence that maybe some of the maple programmers have such an objective, but i do tend to misinterpret everything all the time.

Is there any way we can get maple to tell us which variable we are recursively assigning?
