MacNQC uses the following packages:
This section describes the menus in the MacNQC application.2.1 About Menu
Display the about box dialog which has the version numbers on MacNQC and NQC displayed in it.
Creates a new untitled text document window.
Use the Open File Dialog to select an existing text file to open and create a document window.
The Open Recent hierarchical submenu contains a list of files you have opened recently. To open one of these files, choose it from the Open Recent submenu. MacNQC remembers the most recent eight files that were opened. If the menu item is greyed out then the file is not accessible (renamed, moved, or thrown out).
Close the top most window. If the window is a text document that has not been saved, a dialog will be presented to ask if the document should be saved.
The text document is saved. If the document does not have a name the Save File Dialog is presented so that the text document can be given a name.
The Save File Dialog is presented so that the text document can be given a name.
The current contents of the text document is replaced with the last saved version.
Show the standard Page Setup dialog.
Show the standard Print dialog and if OK is pressed, print the document on the selected printer.
Quit the application.
MacNQC provides the ability to undo multiple edits, one action at a time. The number of edits that may be undone is limited only by available memory.
The Undo command essentially reverses any change you may have made to the content of your file. Each action, which is bounded by a mouse click or arrow key, is one undo-able incident.
MacNQC also supports multiple Redos. If you havenŐt made any changes after performing an Undo, you can redo each action, in order, by selecting that command from the Edit menu, or typing Command- Shift-Z. However,once you perform a new action, you cannot redo any actions that you undid before you made that change.
Removes the selected text from the window and stores it on the Clipboard.
Copies the selected text from the window and stores it on the Clipboard.
Inserts the text stored on the Clipboard at the insertion point in the window. If there is a selection, pasting replaces the selection with the contents of the Clipboard.
Removes the selected text from the window.
Selects all of the text in the window.
There are five targets available. They are CyberMaster, RCX, RCX2 which is the RCX running the 2.0 firmware, Scout and Spybotics.
Defining the target has several effects:
The default target is RCX.188.8.131.52.2 Use NQC 1.0 APIs
This option make NQC compatible with version 1.3 of the NQC compiler. This includes some changes in syntax as well as the 1.3 APIs for the RCX. Default is off
If this option is on then include the source code in the disassembly. Default is on.
With this option on, if the program has been successfully compiled and downloaded into the RCX, then a run command is sent. The default is off.
When this option is on the "Includes" folder in the MacNQC folder is searched for the included file if the file has not been found in the same folder as the source file. The default is off.
This popup is used to select how MacNQC will communicate to the RCX.
If this option is on then the firmware is downloaded at four times the normal speed. It is not always successful and is not available when using the USB Tower on OS9. Default is off.
This option make the datalog output more verbose. Default is off.
If the program hangs when downloading, Turn this option off. (OSX and serial only) Default is on.
This options sets the IR mode on the RCX to near or far. Default is near.
The popup menu chooses which font will be used in the source and disassemble windows.
Sets the size of the font used in the source and disassemble windows.
Sets the width of a tab to the number of spaces entered.
When this option is selected, pressing Return automatically inserts tabs to indent the new line to the same level as the previous line.
The contents of the file that is being compiled will be saved if this option is on. Default is on.
If this option is on then tooltips will be shown for the toolbar. Default is on.
The default color of the text. The default is black.
The default color of the background of the window. The default is white.
This option turns on the syntax coloring. The default is on.
The default color of the text in a comment. Comments start with "/*" and end with "*/" and can be multi-lined. An alternate way of doing comments is to use "//" which is a comment to the end of the line. The default is red.
The default color of the language keywords (i.e. if, else, while...) . The default is blue.
The default color of the RCX constants (i.e. SENSOR_1, OUT_B, LIGHT_OFF...) . The default is purple.
The default color of the RCX keywords (i.e. SetSensor, OnFwd, Program...) . The default is green.
On OS 8 and 9 the look and contents of this dialog will depend on InputSprockets and which joystick you have connected to your computer.
On OS 10 the dialog will look like this:
184.108.40.206 Find String

This is the text that will be substituted.
Finds the first occurrence of the find string in the active window.
Finds the first occurrence of the find string in the active window after the current insertion point and replaces it with the replace string.
Replaces every occurrence of the find string in the active window with the replace string.
When this checkbox is selected, the find string is matched only if it is surrounded in the document text by word-break characters (white space or punctuation). Otherwise, the find string is matched anywhere in the text.
When this checkbox is selected, Uppercase and lowercase letters are treated as different letters. Otherwise, uppercase and lowercase letters are treated as if they were the same.
