TraceScan (Built-in Mathematica Symbol)

TraceScan[f, expr] applies f to all expressions used in the evaluation of expr. TraceScan[f, expr, form] includes only those expressions which match form. TraceScan[f, expr, ...

TraceOff (Built-in Mathematica Symbol)

TraceOff is an option for Trace and related functions which specifies forms inside which tracing should be switched off.

TraceDepth (Built-in Mathematica Symbol)

TraceDepth is an option for Trace and related functions which specifies the maximum nesting of evaluation chains that are to be included.

TraceOn (Built-in Mathematica Symbol)

TraceOn is an option for Trace and related functions which specifies when tracing should be switched on.

$IterationLimit (Built-in Mathematica Symbol)

$IterationLimit gives the maximum length of evaluation chain used in trying to evaluate any expression.

SequenceHold (Built-in Mathematica Symbol)

SequenceHold is an attribute that specifies that Sequence objects appearing in the arguments of a function should not automatically be flattened out.

RuleDelayed (Built-in Mathematica Symbol)

lhs :> rhs or lhs :> rhs represents a rule that transforms lhs to rhs, evaluating rhs only after the rule is used.

OwnValues (Built-in Mathematica Symbol)

OwnValues[x] gives the rule corresponding to any ownvalue defined for the symbol x.

Parallelize (Built-in Mathematica Symbol)

Parallelize[expr] evaluates expr using automatic parallelization.

UpValues (Built-in Mathematica Symbol)

UpValues[f] gives a list of transformation rules corresponding to all upvalues defined for the symbol f.
