DISPLAY MEMORY Command

  • Article

Displays the current contents of variables and arrays.

DISPLAY MEMORY [LIKE FileSkeleton]
   [TO PRINTER [PROMPT] | TO FILE FileName [ADDITIVE]] [NOCONSOLE]

Parameters

  • LIKE FileSkeleton
    Displays information about variables and arrays that match the skeleton pattern FileSkeleton. If you include LIKE FileSkeleton, Microsoft Visual FoxPro displays only the contents of variables and arrays that match FileSkeleton. FileSkeleton supports wildcards such as ? and *. For example, to display all variables that begin with the letter A, issue:

    DISPLAY MEMORY LIKE A*

  • TO PRINTER [PROMPT]
    Directs output from DISPLAY MEMORY to a printer.

    You can include the optional PROMPT clause to display a dialog box before printing starts. In this dialog box, you can adjust printer settings, including the number of copies and page numbers to print. The printer settings that you can adjust depend on the currently installed printer driver. Place the PROMPT keyword immediately after TO PRINTER.

  • TO FILE FileName
    Directs output from DISPLAY MEMORY to the file specified with FileName. If the file already exists and SET SAFETY is ON, you are asked if you want to overwrite the file.

  • ADDITIVE
    Appends to the end of the named file. If you omit ADDITIVE, then the file is overwritten with the value of the expression.

  • NOCONSOLE
    Suppresses output to the main Visual FoxPro window or to the active user-defined window.

Remarks

DISPLAY MEMORY shows the name, type, contents, and status of all currently defined variables and variable arrays. It also displays the number of variables defined, the number of bytes used, and the number of additional variables available. Note that the number of bytes used represents memory used by character type variables. Character type variables are the only type of variables that require additional memory beyond that allocated by the variable count specified with the MVCOUNT configuration item.

Information about system variables, menus, menu bars, menu titles, and windows is also displayed.

Example

In the following example, several variables are created and assigned values. DISPLAY MEMORY first displays all variables that begin with "sam" and then displays all variables that contain five letters and end with "exit."

STORE 'Goodbye' TO sample1
STORE 'Hello' TO sample2
STORE .T. TO texit
STORE .F. TO mexit

CLEAR
DISPLAY MEMORY LIKE sam*
DISPLAY MEMORY LIKE ?exit
