See the section on saturation support (section SaturationSupport) for more information on the effect of this directive. 1.1.40 $SMARTLINK : Use smartlinking A unit that is compiled in the {$SMARTLINK ON} You can specify as many symbols on the command line as you want. The supported assembler constructs are a subset of the normal assembly syntax. wasm assembler for the Watcom assembler. 1.1.34 $P or $OPENSTRINGS : Use open strings 1.1.35 $PACKENUM : Minimum enumeration type size This directive tells the compiler the minimum number of bytes

ord returns ASCII-code of a character, while chr converts given ASCII-code into a character. Predefined macros . The AT&T inline assembler supports the following macros : __RESULT represents the function result return value. __SELF represents the object method pointer in methods. __OLDEBP represents the old base pointer in i don't have a 286 or a p1/90 and i dont' have problems on my p3/450..: : //Noam: There is away of handling this....I had just recently had to do this

In table (Symbols) , a list of pre-defined symbols is given2.1. By default, $GOTO OFF is assumed. As an example, : the following piece of code : {$F+} Procedure TestProc; begin Writeln ('Hello From TestProc'); end; begin testProc end. This replacement works recursive, meaning that when the compiler expanded one of your macros, it will look at the resulting expression again to see if another replacement can be made.

And, since 0 is not equal to one, program keeps subtracting. Compiler and RTL source tree structure B.1 The compiler source tree C. By default, from version 0.9.8 of the compiler on, the compiler predefines three macros, containing the version number, the release number and the patch number. In addition to the Delphi cdecl construct, Free Pascal also supports the popstack directive; it is nearly the same a the cdecl directive, only it still mangles the name, i.e.

The compiler will immediatly stop the compilation process. The default alignment (which can be selected with DEFAULT) is 2, contrary to Turbo Pascal, where it is 1. The packages and runtime library come under a modified Library GNU Public License to allow the use of static libraries when creating applications. If you are not sure, it is better practice to use makefiles and makefile variables. 1.2.16 $W or $STACKFRAMES : Generate stackframes The {$W} switch directove controls the generation of stackframes.

Contrary to the command-line option -vn this is a local switch, this is useful for checking parts of your code. 1.1.33 $OUTPUT_FORMAT : Specify the output format {$OUTPUT_FORMAT format} has the Creates the following output : This program was comilped at 17:40:18 on 1998/09/09 By michael Compiler version : 0.99.7 Target CPU : i386 1.1.24 $I386_XXX : Specify assembler format This switch The behaviour in this case depends on the setting of ReturnNilIfGrowHeapFails. It describes some of the peculiarities of the Free Pascal compiler, and provides a glimpse of how the compiler generates its code, and how you can change the generated code.

Telling the compiler which registers have changed, is done by specifying a set of register names behind an assembly block, as follows: asm ... This directive is equivalent to the -Fu command-line switch. Formats generated by the x86 compiler . to see whether the stack has grown beyond its maximally allowed size.

for example {$INCLUDEPATH ../inc;../i386} {$I} Will add the directories ../inc and ../i386 to the include path of the compiler. Program Polynomial; type arrayOfInt = Array[1..21] of Integer; biggerArrayOfInt = Array[1..41] of Integer; function isNumber(c : Char): Boolean; var res : Boolean; code : Longint; begin code := Ord(c); if ((code Examples: mov al,byte ptr ['c'] -- not allowed. The best way to learn about the way the RTL is implemented is from the sources themselves.

It also will not describe the inner workings of the Run-Time Library (RTL). Notes: The order of terms is important contrary to Turbo Pascal.

The Intel inline assembler supports the following macros : @Result represents the function result return value. Contrary to Turbo Pascal where memory sizes specifiers can be practically anywhere, the Free Pascal Intel inline assembler requires memory size specifiers to be outside the brackets.

This means that you cannot use variables or constants that are defined in the source. The compiler will immediatly stop the compilation process. 1.1.11 $GOTO : Support Goto and Label If {$GOTO ON} is specified, the compiler will support Goto statements and Label declarations. It can take the values 1,2,4 and 8. Join them; it only takes a minute: Sign up How to fix run-time error 201 up vote 0 down vote favorite help me, please.

In summary the repeat is done 65536 +/-1 times. This also means that you cannot call this procedure or function from your own program, since your program uses the Pascal calling convention. This means that if you haven't turned on warning messages, the warning will not e displayed. You can use these symbols to differentiate between different versions of the compiler, and between different compilers.

Finally, the last column specifies if registers are used to pass parameters to the function. Please note that Free Pascalprovides a growing heap, i.e.
