PRB: Memory Not Displayed Correctly for Numeric Data

Last reviewed: June 27, 1995
Article ID: Q126271

The information in this article applies to:

Microsoft FoxPro for Windows, version 2.6a

SYMPTOMS

When you use the DISPLAY MEMORY command to find out how much memory is being used for memory variables, the value displayed for numeric variables is incorrect.

CAUSE

The DISPLAY MEMORY command is only intended to display the memory taken by string data, which varies in length. Other data types, such as numerical, are stored within the memory variable itself which is a fixed-size structure.

STATUS

This behavior is by design.

MORE INFORMATION

Steps to Reproduce Behavior

Type the following commands in the Command window:

SET PDSETUP TO RELEASE _PDPARMS CLEAR MEMORY

MVAR1=12345 MVAR2=4567 DISPLAY MEMORY

The following information regarding MVAR1 and MVAR2 is displayed:

   MVAR1   PUB   N   12345......
   MVAR2   PUB   N   45678.......
   2 variables defined,     0 bytes used

Type the following commands in the Command window:
CLEAR MEMORY MVAR3="ABCD" MVAR4="XYZ" DISPLAY MEMORY
The following information regarding MVAR3 and MVAR4 is displayed:
```
   MVAR3  PUB   C   "ABCD"

   2 variables defined,     21 bytes used
```
