Description

Synopsis

Usage:

listLocalSymbols f
Inputs:
- f, an instance of the type Pseudocode, a symbol, a dictionary, or a function
Outputs:
- a net, a compact display of the symbols in the local dictionaries attached to the closure f, and their values

i1 : x:=3; y:="hi there"; z:=2^30; f = x->x;

i5 : listLocalSymbols f

o5 = symbol  class   value       location of symbol
     ------  -----   -----       ------------------

     y       String  "hi there"  stdio:1:6-1:7     
     z       ZZ      1073741824  stdio:1:21-1:22

i6 : listLocalSymbols symbol x

o6 = symbol  class   value       location of symbol
     ------  -----   -----       ------------------
     x       ZZ      3           stdio:1:0-1:1

Synopsis

Usage:

listLocalSymbols
Outputs:
- a net, a compact display of the symbols in the local dictionaries attached to current

This usage works only in the debugger, where current has a non-null value.

Synopsis

Usage:

listLocalSymbols(X,f)
Inputs:
- X, a type
- f, an instance of the type Pseudocode, a symbol, a dictionary, or a function
Outputs:
- a net, a compact display of the symbols in the local dictionaries attached to the closure f, and their values, provided their values are instances of the type X
