CA-Clipper Compiler--CLIPPER.EXE Compiles one or more program files (.prg) containing procedures and user- defined functions to form an object file (.OBJ). ------------------------------------------------------------------------------ CLIPPER [<sourceFile> | @<scriptFile> [<option list>]] Arguments <scriptFile> is the name of an ASCII text file containing a list of source files to compile into a single object file. The default extension for this file is (.clp). <option list> is a list of one or more options to control the course of the compilation, all of which are described below. To get a list of options, specify the compiler command line with no arguments. Compiler Options All options are shown in uppercase preceded by a slash (/). Note, however, that options are not case-sensitive and that you can replace the slash with a dash (-) if you prefer. Some compiler options have arguments. If an option has arguments, specify them after the option, with no space between the option and its first argument. /A Declares any variable included in a PRIVATE, PUBLIC, or PARAMETERS statement as MEMVAR. /B Includes debugging information in the object file. /D
[=Defines an identifier to the preprocessor with ] assigned to the if specified. /ES[ ]Specifies the severity level of warnings. If is 0 or omitted, the compiler does not set the DOS ERRORLEVEL upon exit if warnings are encountered. This is the default behavior of the compiler. If is 1, the compiler sets the DOS ERRORLEVEL upon exit if warnings are encountered but still generates an .OBJ file. If is 2, the compiler sets the DOS ERRORLEVEL upon exit if warnings are encountered and does not generate an .OBJ file. This effectively promotes warnings to error status. /I Adds the specified directory to the front of the INCLUDE path list. Multiple /I options can be specified in the same compiler session to specify several header file search directories. /L Excludes the program source code line numbers from the object file. /M Compiles only the current program file (.prg) suppressing automatic search for program files (.prg) referenced in a program file with the DO, SET FORMAT, and SET PROCEDURE commands. /N Suppresses the automatic definition of a procedure with the same name as the program file (.prg). /O Defines the name and/or location of the output object file. /P Preprocesses the program file (.prg) and copying the result to an output file with a (.ppo) extension. /Q Prevents line numbers from displaying while compiling. /R[ ]Embeds a library search request in the object file. If /R is specified without name, the default requests for CLIPPER.LIB, EXTEND.LIB, DBFNTX.LIB, and TERMINAL.LIB are suppressed. Multiple /R options can be specified in the same compiler session to embed more than one library request. /S Checks the syntax of the current (.prg) file and no object file is generated. /T Specifies a different directory for temporary files generated during compilation. /U[ ]Identifies an alternate standard header file to preprocess in place of the supplied STD.CH which is used automatically. /V Forces the compiler to assume all references to undeclared or unaliased variable names are public or private variables. /W Generates warning messages for undeclared or unaliased (ambiguous) variable references. /Z Suppresses shortcutting optimizations on the logical operators .AND. and .OR. This option is provided as an aid to isolating code that depends on the behavior of older versions of CA-Clipper.

CA-Compiler - Arguments Listing & Compiler Options
Welcome to Clipper... Clipper... Clipper
In 1997, then using Delphi 3, I had already created 32-bits Windows applications for HRIS, ERP and CRM. In 2007, using Ruby on Rails, an AJAX powered CRM site running on Apache & MySQL was created and I am now using Visual Studio .Net 2008 to create web-based projects and Delphi 7 for Win32 applications using SQL2005 & DBFCDX.
So, why then am I reviving the Original Clipper... Clipper... Clipper via a Blog as CA-Clipper is a programming language for the DOS world ? Believe it or not, there are still some clients using my mission-critical CA-Clipper applications for DOS installed in the late 80's and up to the mid 90's. This is testimony to CA-Clipper's robustness as a language :-)
With the widespread introduction of Windows 7 64-bits as the standard O/S for new Windows based PCs & Notebooks, CA-Clipper EXE simply will not work and it has become imperative for Clipper programmers to migrate immediately to Harbour to build 32/64 bits EXEs
Since 28th January 2009, this blog has been read by 134,389 (10/3/11 - 39,277) unique visitors (of which 45,151 (10/3/11 - 13,929) are returning visitors) from 103 countries and 1,574 cities & towns in Europe (37; 764 cities), North America (3; 373 cities) , Central America & Caribeans (6; 13 cities), South America(10; 226 cities), Africa & Middle-East (12; 44 cities) , Asia-Pacific (21; 175 cities). So, obviously Clipper is Alive & Well : -)
TIA & Enjoy ! (10th October 2012, 11:05; 13th November 2015)
