Summary:System and method for analyzing a graphical program. A graphical program is displayed on a display. A semantic edit operation is performed on the graphical program in response to user input. The semantic edit operation is performed by a first process. Semantic analysis of the graphical program is performed by a second process in response to performing the semantic edit operation, where the second process is asynchronous with respect to the first process. Results from the semantic analysis of the graphical program are displayed in response to completion of the semantic analysis. If during the semantic analysis, another semantic edit operation is performed on the graphical program, the semantic analysis may be preemptively terminated and re-initiated. Displaying results from the semantic analysis of the graphical program may then include displaying results from the re-initiated semantic analysis of the graphical program in response to completion of the re-initiated semantic analysis.
