Probably 'scrip.
Much puctuation has been modified by the adoption of 'open punctuation' originally used to reduce typewriter keystrokes in the Civil Service. It upsets those who think that grammatical conventions are unalterable: most of the world don't give a toss.

Compare: Mr J.A.Smith B.A. Cert.Ed. with: Mr J A Smith BA CertEd I prefer the latter.

Dr and Mr are contractions ie they contain the first and last letters of the shortened word - they should never have a full stop (period, point).

Should you have apostrophes in P's and Q's or photo's?
