A debugger for support of the debugging of a program, an array data displaying method in the debugger, and a recording medium having an array data displaying program in the debugger are disclosed. A debugger system may be provided with a data save unit and a display control unit so that a command is issued to a source program at a breakpoint to save array data. Next, an instruction for display of the saved data is made to display the data on a display unit. Thereby, the contents of an array can be saved without changing a source and the saving and display of array data can be performed asynchronously. Also, the debugger system may be provided with an array construction control unit, a shared element control unit and a display element sampling unit so that an array distributed to a plurality of processes is constructed by the array construction unit and is displayed in the form of a graph with the trimming performed by the display element sampling unit down to the proper number of elements. Thereby, in the debugging of a multi-process program, the grasp of the whole of an array distributed to each process can be facilitated.
