MS-DOS         | Windows kbprb The information in this article applies to:
 * Microsoft FoxPro for MS-DOS, versions 2.0, 2.5, and 2.5a
 * Microsoft FoxPro for Windows, versions 2.5 and 2.5a

SYMPTOMS
In a stand-alone executable file, when a macro substitution contains a FoxPro command or a command clause, a &quot;Feature not available&quot; error message occurs.

CAUSE
When FoxPro creates a stand-alone executable file, it scans the file for FoxPro commands in the project and places the necessary code in the file. When a macro substitution statement is executed, the code evaluates the variable and compiles and executes the command. If the variable contains a command or part of a command, the necessary code may not be available in the executable file.

RESOLUTION
Create another program or procedure in the project that contains the possible combinations of FoxPro commands that the application can create through macro substitutions. Even though this program or procedure is never called, its presence forces FoxPro to include in the .EXE file all the code required to run the macro substitution commands.

MORE INFORMATION
The following code example demonstrates this error. Because the code does not explicitly issue the PACK command, FoxPro does not include the required code in the stand-alone .EXE file; therefore, an attempt to run the PACK command from the macro substitution fails.
