- Bit manipulations: The BP style bit shift operators
`shl`

and`shr`

exist in GPC as well as bitwise`and`

,`or`

,`xor`

and`not`

for integer values.2#100101 and (1 shl 5) = 2#100000

GPC also supports

`and`

,`or`

,`xor`

and`not`

as procedures:program BitOperatorProcedureDemo; var x: Integer; begin x := 7; and (x, 14); { sets x to 6 } xor (x, 3); { sets x to 5 } end.

- Succ, Pred: The standard functions Succ and Pred exist in GPC and accept a second parameter.
- Increment, decrement:
The BP built-in Procedures
`Inc`

and`Dec`

exist in GPC.program IncDecDemo; var i: Integer; c: Char; begin Inc (i); { i := i + 1; } Dec (i, 7); { i := i - 7; } Inc (c, 3); { c := Succ (c, 3); } end.

`Min`

,`Max`

: These are a GNU Pascal extension and work for reals as well as for ordinal types. Mixing reals and integers is okay, the result is real then.
