A surrogate key is frequently a sequential number (e.g. a Sybase or SQL Server "identity column", a PostgreSQL or Informix serial, an Oracle or SQL Server SEQUENCE or a column defined with AUTO_INCREMENT in MySQL). Some databases provide UUID/GUID as a possible data type for surrogate keys (e.g. PostgreSQL UUID [3] or SQL Server ...
This is the size used for start+increment and random AutoNumbers. For replication ID AutoNumbers, the FieldSize property of the field is changed from long integer to Replication ID. [2] If an AutoNumber is a long integer, the NewValues property determines whether it is of the start+increment or random form. The values that this property can ...
The post-increment and post-decrement operators increase (or decrease) the value of their operand by 1, but the value of the expression is the operand's value prior to the increment (or decrement) operation. In languages where increment/decrement is not an expression (e.g., Go), only one version is needed (in the case of Go, post operators only).

When auto-increment is available (most models), it updates the entire 24-bit address including RAMPZ. (Rare) models with >128 KiB of ROM have a 3-byte program counter.

That is, fetch-and-add performs the following operation: increment the value at address x by a, where x is a memory location and a is some value, and return the original value at x.
