SI top-level constant

String const SI

Shift-In.

SI is used for code extension purposes. It causes the meanings of the bit combinations following it in the data stream to be changed.

The use of SI is defined in Standard ECMA-35.

NOTE

SI is used in 7-bit environments only; in 8-bit environments LOCKING-SHIFT ZERO (LS0) is used instead.

Locking-Shift Zero.

LS0 is used for code extension purposes. It causes the meanings of the bit combinations following it in the data stream to be changed.

The use of LS0 is defined in Standard ECMA-35.

NOTE

LS0 is used in 8-bit environments only; in 7-bit environments SHIFT-IN (SI) is used instead.

Implementation

const String SI = '\x0F';
