Abstract

This article describes a program that takes assembler language source statements and creates flow-chart statements that then may be used to make a flow chart. (Image Omitted) In the technique disclosed herein, each statement that could result in a branch (JMP), a decision (JNZ, JZ), a call to a routine (CALL) or a return from a routine (RET) forms a flow-chart statement that will create the proper flow-chart block. Whenever a flow-chart statement is created by a decision source statement, the next statement is also made into a flow-chart statement to help follow the flow. Since labels are used, any statement with a label will create some flow-chart block. If there is any sequence of more than four source statements other than those previously mentioned, it will create a process flow-chart block.

Program Source Statements to Flow-Chart Statements Program

This article describes a program that takes assembler language source statements and creates flow-chart statements that then may be used to make a flow chart.

(Image Omitted)

In the technique disclosed herein, each statement that could result in a branch (JMP), a decision (JNZ, JZ), a call to a routine (CALL) or a return from a routine (RET) forms a flow-chart statement that will create the proper flow-chart block. Whenever a flow-chart statement is created by a decision source statement, the next statement is also made into a flow-chart statement to help follow the flow. Since labels are used, any statement with a label will create some flow-chart block. If there is any sequence of more than four source statements other than those previously mentioned, it will create a process flow-chart block. This will prevent creating a flow-chart statement from every source statement. The comment on the source statement is used for the comment in the flow-chart block. Figs. 1A and 1B comprise a flow chart of this technique.
