100% Compatible with Tcl

Highlights in ActiveTcl 8.5

• Speed

  8.5 now runs 10% faster than 8.4 with bytecode improvements, object caching and reduced memory usage.
• Bignums

  Tcl now supports arbitrary-precision integers, which improves math operations on large integers.
• Safer interps

  Tcl's powerful safe interpreter mechanism now has improved control of time and command limits in slave interpreters.
• clock command

  More robust implementation of command for specifying time, with significant l10n and i18n improvements.
• dict command

  New data structure that allows access to data by value rather than a variable name, which is substantially faster.
• Additional improvements

  Faster list search, new and improved mathematics procedures, anonymous procedures, new ways to package Tcl extensions, Tcl-level custom channel types, file and line location information for each command, and more.
