As it is, you pass the designation and MakeMPC looks for a pure number less than 100000 to decide to produce the numbered MP format. But Now the 5-char "number" can be encoded for numbers 100000 and up. Need smarter code here to try converting the encoded number, and only if that fails, then deciding it's a designation.

It alrady does this. Tested with numerics greater than 100000 and it definitely encodes the number correctly. The problem was the user passing it as a string and not a 32-bit integer.

Will instead accept numbers greater than 99999 and encode them for the MPC report within PinPoint.
