Single Key Function Selection: 1 - Single solid line & regular text 2 - Double solid line & small text 3 - Triple solid line & large text 4 - Dotted line 5 - Dashed line G - Snap on/off O - Absolute/Relative coordinate Special keys: Ctrl - Show contents of dotted box Alt - Stretch dotted box Single key menu item selection: Type upper case letter. TurboFlow Changes: ----------------- 1. Extend or shrink lines: The Trim command in the Edit menu allows you to move a control point of any element to a new location. It is useful for extending or shrinking existing lines. You should first select the control point by clicking the mouse button near the point to be changed, then move your cursor and click at the new location. 2. New Icons: 1. The first icon in the DRAW menu allows you to generate 3 objects: Text, Process box, and a line with ending arrowhead pointing downward all at once. The text is left-aligned. 2. The second icon in the DRAW menu allows you to generates 3 objects: Text, decision box, and a line with ending arrowhead pointing downward all at once. The text is self-centered. 3. New Libraries: Two symbol libraries are added: FLOW1.LBR and DRAW0.LBR. The symbols contained in FLOW1.LBR are listed below: 11.Box1 21.Line 31.Crossover 41.Wave 12.Box2 22.Line 32.Bezier curve 42.Line 13.Diamond 23.Line 33.Half circle 43.Dim 14.Triangle 24.Line 34.Quarter cir 44.Mark 15.Circle 25.Line 35.Partial cir 45.Text 16.Oval 26.Line 36.Round corner 46.Fill 17.Line 27.Curve 37.Long curve 47.Fill 4. Configuration File: A configuration file consists of commands that are interpreted by TurboFlow after the drawing is started. Several typical applications for this feature are listed below: a. Set default paper size and orientation. b. Load special symbol library. c. Append symbol libraries to the main menu. d. Self running demo. The configuration file is invoked by specifying the file name as the parameter when loading EZCAD.COM. This can be accomplished by loading each driver program manually, by editing the FLOW.BAT file, by editing the LOAD.BAT file which is invoked by the FLOW.BAT file, or by typing the following line: LOAD CLS TBFLOW filename.CFG The configuration commands are listed below: Command: | The "|" character is the starting/ending character for messages that are displayed in the dialogue box. Command: ; The ";" character indicates a comment line. Command: @ x,y Cursor positioning. x is the horizontal pixel coordinate, y is the vertical pixel coordinate. The origin (0,0) of the pixel coordinate is the lower left corner of the screen. Command: ADDLBR filename Add a libary to the main menu, up to 11 can be added. File name extension must be specified. Command: CLEAR Screen clear. Command: CANCEL Equivalent to pressing the Cancel button. Command: END End of configuration file. Command: LDLBR filename Equivalent to the LOAD LIBRARY FILE Command. File name extension must be specified. Command: LDFILE filename Equivalent to the LOAD FILE command. A drawing is loaded. File name extension must be specified. Command: MENU=n Selecting the current menu or submenu displayed on the screen. The first item is item 0, the next item down is item 1, etc. Command: PAN Pan the screen if necessary. Command: PSIZE=n Set current drawing paper size according to the followling table: n dimension code -- ------------ ---- 0 11.0 X 8.5 A 1 17.0 X 11.0 B 2 22.0 X 17.0 C 3 34.0 X 22.0 D 4 44.0 X 34.0 E 5 14.0 X 11.0 W 6 8.5 X 11.0 A' 7 11.0 X 17.0 B' 8 17.0 X 22.0 C' 9 22.0 X 34.0 D' 10 34.0 X 44.0 E' 11 11.0 X 14.0 W' 12 14.0 X 22.0 X2 13 14.0 X 33.0 X3 14 14.0 X 44.0 X4 15 22.0 X 14.0 X2' 16 33.0 X 14.0 X3' 17 44.0 X 14.0 X4' Command: RESET Clear the drawing. Command: REFRESH Refresh the drawing area of the screen, usually used to erase the dialogue box. Command: RETURN Return to the interpreter. Let previous commands be visually displayed before interpreting the next command. Command: SELECT Equivalent to pressing the Select button. Command: SETMENU=n The next menu item selected by the WAIT SELECT command will be n no matter what the user selects. Command: WAIT=n Wait for n/10 seconds or until a button press. Command: WAIT SELECT Wait indefinitely until the Select button press. Command: WAIT CANCEL Wait indefinetely until the Cancel button press.
