How to Pass Parameters from MS-DOS to FoxPro for MS-DOS

• Microsoft FoxPro for MS-DOS, versions 1.02, 2.0, 2.5, and 2.5a

SUMMARY

The method used to pass parameters from the MS-DOS prompt to Microsoft FoxPro for MS-DOS differs between version 1.02 and later versions. Below are the requirements for each version.

MORE INFORMATION

The following rules apply to FoxPro versions 2.0 and later for MS-DOS:

• Do not enclose Character-type parameters in single quotation marks.
• Separate multiple parameters with a space.
• Each parameter is received in the Character type. Use the conversion functions when parameters have other types.
• If an application is invoked in the FoxPro command line, the application must begin with a PARAMETERS statement.

  For example, in FoxPro 2.0 and later, use the following command from the MS-DOS prompt:

        FOXPROL test.prg hello 24 01/01/89 .T.
  

  The contents of TEST.PRG are listed below:

        Test.prg    && For FoxPro 2.0 and 2.5
        parameters x,y,z
  
        wait window "This is parameter 1: "+x
        wait window "This is parameter 2: "+y
        wait window "This is parameter 3: "+z
  
  

• Enclose character type parameters in single quotation marks.
• The WITH keyword must be used when starting FoxPro.
• Use a comma to separate multiple parameters.
• Any type of parameter (logical, numeric, and so on) can be used.

  For example, in FoxPro 1.02 use the following command from the MS-DOS prompt:

        FOXPROLN test.prg WITH 'hello', 24, {01/01/89}, .T.
  

  The contents of TEST.PRG are listed below:

        Test.prg    && For FoxPro 1.02
        parameters x,y,z
  
        wait window "This is parameter 1: "+x
        wait window "This is parameter 2: "+str(y)
        wait window "This is parameter 3: "+DTOC(z)
