Closing notepad files In QuickC 2.5, closing the Notepad window saves and frees the file. In QuickC 2.0, when you load a file in the Notepad window and then close it, the file is not freed. The file therefore cannot be loaded into the Program window.%@CR:C6A00010006 @% %@NL@% %@2@%%@CR:C6A00010007 @%%@AB@%1.2 View Menu Changes%@AE@%%@EH@%%@NL@% %@NL@% The following change is found in the View menu:%@CR:C6A00010008 @%%@CR:C6A00010009 @%%@CR:C6A00010010 @% %@NL@% %@NL@% %@AB@%Change%@AE@% %@AB@%Description%@AE@% %@AB@%────────────────────────────────────────────────────────────────────────────%@AE@%%@NL@% Registers window The Registers window displayed with the Windows command in the View menu has been modified to display information about the math coprocessor chip and emulator. Additionally, pressing TAB moves the cursor forward between modifiable fields, while pressing SHIFT+TAB moves the cursor backward between modifiable fields. Pressing ENTER or double-clicking the Left mouse button allows you to modify a register. %@NL@% %@2@%%@CR:C6A00010011 @%%@AB@%1.3 Search Menu Changes%@AE@%%@EH@%%@NL@% %@NL@% The following changes are found in the Search menu:%@CR:C6A00010012 @%%@CR:C6A00010013 @%%@CR:C6A00010014 @% %@NL@% %@NL@% %@AB@%Change%@AE@% %@AB@%Description%@AE@% %@AB@%────────────────────────────────────────────────────────────────────────────%@AE@%%@NL@% New Go to command The Go to... command has been added to the Search menu. This command displays a dialog box into which you type a desired line number. Then QuickC moves the cursor to that line.%@CR:C6A00010015 @% Selected text shortcut key Since the backslash key ( \ ) is not available on standard European keyboards, the shortcut key for the Selected Text command has been changed from CTRL+\ to CTRL+F3. CTRL+\ is now the shortcut key for the Find command in the Search menu. The effect of CTRL+\ can be modified with the MKKEY utility. %@NL@% %@2@%%@CR:C6A00010016 @%%@AB@%1.4 Make Menu Changes%@AE@%%@EH@%%@NL@% %@NL@% The following changes are found in the Make menu:%@CR:C6A00010017 @%%@CR:C6A00010018 @%%@CR:C6A00010019 @% %@NL@% %@NL@% %@AB@%Change%@AE@% %@AB@%Description%@AE@% %@AB@%────────────────────────────────────────────────────────────────────────────%@AE@%%@NL@% Canceling the build process With version 2.5, pressing ESC cancels a compile, but not a link. The dialog box tells you to press CTRL+BREAK to cancel both compiling and linking. Previously, when either the Build or the Rebuild All command was given, the dialog box said to press ESC to cancel compiling and linking.%@CR:C6A00010020 @% .H files in the program list QuickC 2.5 supports adding .H files to the program list with the Edit Program List command. QuickC treats all .C files as dependents of the .H files in the list. If an include file is modified, QuickC performs a full rebuild. If you have hand-edited a makefile to encode .H file dependencies, then QuickC does not display these include files as part of the program list in the Edit Program List dialog box. If QuickC rewrites the hand-edited makefile, these include-file dependencies are not modified.%@CR:C6A00010021 @% %@CR:C6A00010022 @% Alphabetical file File names are now displayed display in the alphabetically in the program list and program list in the dialog box displayed by choosing the Source command in the View menu. Consequently, names of .LIB files are displayed at the end of the list, eliminating the need to scroll over names of files that cannot be opened with the Source command. %@NL@% %@2@%%@CR:C6A00010023 @%%@AB@%1.5 Debug Menu: New Quickwatch Command%@AE@%%@EH@%%@NL@% %@NL@% The Quickwatch command is a new feature in QuickC 2.5. It gives you a faster view of variables and expressions than does the Watch Value command. To use Quickwatch%@CR:C6A00010024 @%%@CR:C6A00010025 @%%@CR:C6A00010026 @%%@CR:C6A00010027 @%%@CR:C6A00010028 @% %@NL@% %@NL@% %@NL@% 1.

Choose the Quickwatch command from the Debug menu or press SHIFT+F9%@NL@% %@NL@% %@NL@% QuickC displays a dialog box with the selected variable or expression along with the current value. See Figure 1.1. %@NL@% %@NL@% %@AU@%(This figure may be found in the printed book.)%@AE@%%@NL@% %@NL@% Instead of placing the cursor on the variable or highlighting the expression you want to watch, you can select Quickwatch, or press SHIFT+F9, and type an expression in the text box of the dialog box. %@NL@% %@NL@% The lower part of the Quickwatch dialog box contains the following buttons: %@NL@% %@NL@% Zoom Modify Value Evaluate Cancel Add Watch Help %@NL@% %@NL@% The Zoom button expands or contracts an array or structure. Zoom displays the values of the array members or structure elements in the List box. To show levels of expansion in the List box, nested elements are indented one space. If the expression has already been expanded, the Zoom button contracts the items. If a variable can be expanded, it has a "+" prefix. If a variable can be contracted, it has a "-" prefix. If the expression cannot be expanded or contracted and Zoom is selected, QuickC beeps. %@NL@% %@NL@% The Evaluate button uses the current expression in the Expression text box as the new base variable. If the expression can be expanded, the Zoom button displays items in the List box. %@NL@% %@NL@% To further expand nested items shown in the List box, select item names with the mouse or cursor. The item names are copied to the Expression text box, and the appropriate values are displayed in the Value text box and the List box. Then you can use the Zoom button to expand or contract the nested items. %@NL@% %@NL@% The Add Watch button adds the current expression to the Watch window. If the expression is already included in the Watch window, Add Watch has no effect. %@NL@% %@NL@% The Modify Value button changes the value of the expression to the value entered in the Value text box. When you select Modify Value, QuickC records and displays the updated value in the List box. %@NL@% %@NL@% The Cancel button closes the Quickwatch dialog box. %@NL@% %@NL@% The Help button displays information about using the Quickwatch dialog box. %@NL@% %@NL@% %@NL@% %@2@%%@CR:C6A00010029 @%%@AB@%1.6 Options Menu Changes%@AE@%%@EH@%%@NL@% %@NL@% The following changes are found in the Options menu:%@CR:C6A00010030 @%%@CR:C6A00010031 @%%@CR:C6A00010032 @% %@NL@% %@NL@% %@AB@%Change%@AE@% %@AB@%Description%@AE@% %@AB@%────────────────────────────────────────────────────────────────────────────%@AE@%%@NL@% Run/Debug command-line length In QuickC 2.5, the Command Line text box limitation in the Run/Debug dialog box accepts up to 126 characters. A warning message is displayed if the length of text exceeds 126 characters. QuickC 2.0 accepts up to 256 characters. However, only the first 126 characters are used. Compiler flags, linker flags, Numerous changes have been made to the and display dialog box changes compiler flags, linker flags, and display dialog boxes. They are described in the following sections. New color command Enhanced options for setting colors in QuickC are described below. %@NL@% %@3@%%@CR:C6A00010033 @%%@AB@%1.6.1 Compiler Flags Dialog-Box Changes%@AE@%%@EH@%%@NL@% %@NL@% The Compiler Flags dialog box, shown in Figure 1.2, contains the following modifications: %@NL@% %@NL@% %@NL@% ■ The Compiler Flags dialog box, displayed by selecting the Compiler Flags button in the Make dialog box, has been modified to support the tiny memory model.%@NL@% %@NL@% ■ The Warning Level option has been changed from a set of option buttons to a text box, and this option now supports warning levels up to 4. If you enter an invalid warning level, QuickC displays a warning message.%@NL@% %@NL@% ■ In QuickC version 2.5, the Full CodeView check box replaces the Line Numbers Only option under Debug Flags in version 2.0. If Full CodeView is checked, QuickC generates complete information on the Microsoft CodeView(R) debugger. If the option is left unchecked, QuickC generates line number information.%@NL@% %@NL@% ■ Three Custom Flags text boxes have been added to the dialog box. They allow you to specify additional Global, Debug, and Release compiler directives. %@NL@% %@NL@% %@STUB@% %@AU@%(This figure may be found in the printed book.)%@AE@%%@NL@% %@NL@% %@NL@% %@NL@% %@3@%%@CR:C6A00010034 @%%@AB@%1.6.2 Linker Flags Dialog-Box Changes%@AE@%%@EH@%%@NL@% %@NL@% The Linker Flags dialog box, shown in Figure 1.3, contains the following changes:%@CR:C6A00010035 @% %@NL@% %@NL@% %@NL@% ■ The Global Flags check boxes contain a new option called Generate .COM File. This option uses the tiny memory model to create .COM files.%@NL@% %@NL@% ■ A new Memory Needs text box allows you to specify the amount of memory to allocate for a program.%@NL@% %@NL@% ■ The new Custom Flags text box allows you to specify additional Global linker directives, as well as those for Debug and Release versions of the program.

If the option is off, tabs are converted to the appropriate number of spaces. Then when the file is saved, leading spaces are converted back to tabs. If the option is on, tabs are always treated as tabs and are never converted to spaces. The default for this option is off, which is equivalent to the QuickC 2.0 method of handling tabs.%@CR:C6A00010037 @%%@CR:C6A00010038 @%%@NL@% %@NL@% ■ The Show 8087 check box controls whether the 8087 registers are displayed in the Registers window.%@NL@% %@NL@% ■ When you check the Save Before Build check box, QuickC saves any changes in open files before it builds the program.%@NL@% %@NL@% %@NL@% %@AU@%(This figure may be found in the printed book.)%@AE@%%@NL@% %@NL@% The Display dialog box no longer contains a color selection option.

The address of the integer contains 32 bits. The size of the address of %@AS@% %@AS@%fp_i %@AE@% is memory model dependent. %@AS@% %@AE@%%@NL@% %@NL@% QuickC 2.0 interprets the declaration as %@NL@% %@NL@% %@AS@% int *far fp_i;%@AE@%%@NL@% %@NL@% where %@AS@% fp_i %@AE@% is a far variable that is a near pointer to an integer. The address of %@AS@% fp_i %@AE@% is 32 bits. The size of the integer's address is indeterminate. %@NL@% %@NL@% This change in handling pointers to type definitions affects type definitions containing %@AB@%_near%@AE@%, %@AB@%_far%@AE@%, %@AB@%_based%@AE@%, and other modifiers. Although these are Microsoft-specific keywords, their new behavior is consistent with the ANSI standard's requirements for the %@AB@%const %@AE@%and %@AB@%volatile %@AE@%keywords. %@NL@% %@NL@% %@NL@% %@3@%%@CR:C6A00020026 @%%@AB@%2.1.6 Identifying Nonstandard Keywords%@AE@%%@EH@%%@NL@% %@NL@% The following modifiers are specific to QuickC; they are not part of the ANSI standard.

This ability results in faster function calls when a QuickC program is built with Microsoft C version 6.0.%@CR:C6A00020048 @% %@NL@% %@NL@% You can define fastcall functions in two ways. Use the %@AB@%_fastcall%@AE@% function attribute to declare an individual function as fastcall: %@NL@% %@NL@% %@AS@% int _fastcall FastFunc( void );%@AE@%%@NL@% %@NL@% Additionally, the /Gr option enables the fastcall function-calling convention for all functions that are not explicitly prototyped with the %@AB@%_cdecl%@AE@%, %@AB@%_pascal%@AE@%, or %@AB@%_fortran %@AE@%attributes. Using /Gr on the command line causes each function in the module to compile as %@AB@%_fastcall%@AE@% unless the function is declared with a conflicting attribute, or the name of the function is %@AB@%main%@AE@%. %@NL@% %@NL@% None of the library functions have the fastcall attribute; their arguments are passed on the stack, not in registers. If you compile with the /Gr option, you must include the correct header file for each library function or write a prototype for the function using the %@AB@%_cdecl%@AE@% attribute. %@NL@% %@NL@% A fastcall function can receive up to three 16-bit arguments. Arguments are passed in the AX, BX, and DX registers. Fastcall arguments are passed in the registers shown below. If you pass one character argument, it is passed in the AL register. If you pass two character arguments, the second argument is passed in DL, and so on. %@NL@% %@NL@% %@AB@%Argument Type%@AE@% %@AB@%Registers%@AE@% %@AB@%────────────────────────────────────────────────────────────────────────────%@AE@%%@NL@% Character AL, DL, BL Short integer AX, DX, BX Near pointer BX, AX, DX Long integer DX:AX ────────────────────────────────────────────────────────────────────────────%@NL@% %@AU@%WARNING%@AE@%%@NL@% %@NL@% Future versions of QuickC may pass fastcall arguments in different registers.%@NL@% ────────────────────────────────────────────────────────────────────────────%@NL@% %@NL@% If all of the registers for a particular type have already been used, or if an argument is not one of the types listed above, it is pushed on the stack as usual. Given an argument list of types %@AB@%long%@AE@%, %@AB@%float%@AE@%, and %@AB@%short%@AE@%, QuickC passes the %@AB@%long %@AE@%in DX:AX, pushes the %@AB@%float%@AE@%, and passes the %@AB@%short %@AE@%in BX. Fastcall functions return any floating-point value on the floating-point processor stack. %@NL@% %@NL@% The treatment of character arguments is also dependent on prototypes. If there is no prototype, the argument is promoted to %@AB@%short%@AE@%. %@NL@% %@NL@% The %@AB@%_fastcall %@AE@%convention is not compatible with any of the following attributes: %@AB@%_interrupt%@AE@%, %@AB@%_saveregs%@AE@%, %@AB@%_export%@AE@%, %@AB@%_cdecl%@AE@%, %@AB@%_fortran%@AE@%, or %@AB@%_pascal%@AE@%.

This rule allows you to access inner members of such nested constructs using fewer variable names. The following example demonstrates this technique using nested structures:%@CR:C6A00020065 @%%@CR:C6A00020066 @%%@CR:C6A00020067 @% %@NL@% %@NL@% %@AS@% #include.h %@AS@% %@AS@% void main( void ) %@AS@% { %@AS@% struct ours %@AS@% { %@AS@% int mine, yours; %@AS@% }; %@AS@% %@AS@% struct mystruct %@AS@% { %@AS@% float bobber; %@AS@% struct ours; %@AS@% char name[9]; %@AS@% } sample; %@AS@% %@AS@% sample.yours = 100; %@AS@% printf( "sample.yours: %i\n", sample.yours ); %@AS@% }%@AE@%%@NL@% %@NL@% The example declares two structure types. The first structure type, named %@AS@% %@AS@%ours%@AE@%, contains two %@AB@%int%@AE@% members. The second, named %@AS@% mystruct%@AE@%, contains three members, one of which is a structure of type %@AS@% ours%@AE@%. %@NL@% %@NL@% The second structure type declares its structure member using only the structure tag %@AS@% ours%@AE@%. It does not supply a variable name after the tag: %@NL@% %@NL@% %@AS@% struct ours;%@AE@%%@NL@% %@NL@% Thus, subsequent parts of the program can access members of the nested structure without specifying a name: %@NL@% %@NL@% %@AS@% sample.yours = 100;%@AE@%%@NL@% %@NL@% In contrast, if the nested structure had been declared using a variable name, as in %@NL@% %@NL@% %@AS@% struct ours var_name;%@AE@%%@NL@% %@NL@% subsequent statements would have to use that name as well: %@NL@% %@NL@% %@AS@% sample.var_name.yours = 100;%@AE@%%@NL@% %@NL@% As you can see, declaring the nested structure without a variable name saves some typing.
