PURPOSE:To separate a group of statements from other groups of statements when the group of statement is displayed, and to display the structure of a program so that it is easily discriminated by men, by analysing the structure of the program and discriminating an assembly of statements which becomes one group in structure. CONSTITUTION:Characters and control codes from a communication line, electronic computer, etc., are inputted into a structure analysing section 2 from an input device 1, and the collation with the grammer of a program and analysis of the structure are peformed at the analysing section 2. The analysed result is sent to a structure discriminating section 4 and it is judged whether the structure is changed by a character string inputted by referring to a structure storing section 3 or not. When the structure is changed, the storing section 3 is rewritten. Thus the most up-to-date data are always stored in the structure section 3 and an assembly of statements is displayed on a display section 5 based on the most up- to-date data stored in the storing section 3. When the group of statements is displayed, the group is separated from other groups and the structure of the program is displayed so that it can be discriminated easily by men. |
