Progress Bar & Prototypes

Ok, my last question(s) on the subject.

Making an attractive progress bar on the bottom of green-screen is very 
simple. (Anyone that wants a .gif of one just e-mail and I'll return a gif 
for you to look at). 

The only variables in the Progress Bar are: Starting time, Total Records, 
Records counted so far, records chosen so far, and Time now.  There is a 
couple lines of code to establish the Percent Counted So Far and also to 
estimate the time remaining.  Then there is a couple more lines to 
concatenate a string to be presented in the Progress Bar screen format. 

My question(s) have to do with making this into a prototype.  For a 
prototype: StartingTime and TimeNow are not Parms.  TotalRecords is a 
parm(but needed only once?) and then RecordsCountedSoFar and 
RecordsChosenSoFar are the only two parms that change as the process runs. 
 As a last step in the cycle one does a WRITE PrgBarFmt to display the 
Progress Bar.

If I understand what all of you are saying then any program could have PR 
D-specs for the Progress Bar and one line of code inside a 
record-reading-processing loop that would be:

   C                    Call 
ProgressBarPR(TotalRecords:RecordsCountedSoFar:RecordsChosenSoFar:MsgFlag)

My questions:

1 - Is this a reasonable usage of the Prototype?
2 - what are the implications for performance?  Will this hurt performance 
as compared to doing the same process within the calling program?
