Abstract:
A method in a computer system for determining an operand for an operator during data entry of the nodes of an intentional program tree, the method comprising:receiving a sequence of tokens, each token indicating a computational construct corresponding to a node of the intentional program tree;when receiving an indication of a selection of a subtree of the intentional program tree, selecting the indicated subtree; andwhen receiving an indication of a next token to be appended to the sequence of tokens,when a subtree is currently selected, identifying the selected subtree as an operand of the operator represented by the next token;when a subtree is not currently selected, identifying according to predefined rules of operator precedence an operand of the operator represented by the next token; andadding a node to the intentional program tree indicating the operator represented by the next token and indicating the identified operandwhereby predefined rules of operator precedence may be overridden by selection of a subtree.
