【摘要】 用 FORTRAN 语言编写了类似高级 BASIC 绘图中窗口和视口语句的子程序,利用《高级语言图形开发功能初探》一文中画线汇编子程序,重新编制了画点和画线子程序,使 FORTRAN 绘图不再受屏幕实际边界的局限,可方便地实现图形的放大,缩小与剪辑.更多还原

【Abstract】 The paper uses Fortran language to compile the subroutine wich is similar to the window and view sentence in BASICA,and rewrites the drawing point and line subroutine with the assembled subroutine of drawing line in the reference one,thus FORTRAN drawing is not limited by the actual border of the screen and is able to enlarge,reduce and cut the graph.更多还原
