programming

Here are some useful programming constructs for controlling the flow of execution.
  • apply -- loop over a list, keeping results
  • if -- condition testing
  • scan -- loop over a list
  • while -- loop control
  • ; -- statement separator

    • Controlling the scope of variables:

  • := -- assignment to and declaring a new local variable
  • global -- using global symbols which have values
  • local -- declaring new local symbols
  • quote -- using symbols which have values

    • Miscellaneous items:

  • -- -- introducing comments
  • addEndFunction -- do something upon exiting
  • addStartFunction -- do something after loading dumped data
  • clearOutput -- release some memory
  • clearAll -- release more memory
  • Command -- top level commands
  • erase -- remove a symbol
  • value -- evaluate a string, symbol, or expression
  • memoize -- memoizing functions
  • using methods -- using methods
  • notImplemented -- 'not implemented yet' error message
  • processArgs -- process optional arguments to functions
  • protect -- protecting the value of a symbol
  • runEndFunctions -- run the ending functions
  • runStartFunctions -- run the starting functions
  • setrecursionlimit -- limits on recursion depth
  • syntax -- the syntax of the language
  • value -- getting values of symbols

    • For internal use only:

  • lineNumber -- the current line number
  • lookupCount -- how many times a symbol has been seen
  • phase -- internal variable for compilation
  • runStartFunctions -- run the start functions
