The difference should be small and on the more esoteric edges of the spec.
The SRM was developed after the VT100, so some things may have
exception cases but VT52 and VT100 capability in latter terminals were
based on VT52 and VT100 behavour by actual testing and also known
behavour.

No, never saw Pascal code in the SRM (it's about 2 inches thick!) nor
have I seen it outside DEC. It was part of the some 203 DEC STDs
such as VAX archectecture, packaging and all manner of other things.
