Thanks for reporting these little annoyances, I'm always looking in the forum for issues like this one to make sure newRPL does not repeat errors from the past.
In this regards, newRPL compiler does not depend on any flags. If you write a number, the number is compiled "as written" by the user, even if it has more digits than the current system precision.
I'm also for flag-free calculations (or as free as possible), ideally a command (or operator) output should be fully determined by its input, no flags should be involved.

Back to the original topic, the exponents limits in newRPL are -30000 to +30000 so 200^300 is not an issue.
200^300 at any given precision gives the 2.03703...E690 with as many digits as you have requested. Setting the system precision to 91 digits is enough to get the exact result, with 90 you lose one digit.
A trailing dot indicates when a result is approximated or exact, which in this case it comes handy to know if you are overflowing the current precision without having to actually look at all the digits.
