Steps to Reproduce the Behavior

NOTE: The following code assumes that you have installed the sample data that ships with Visual FoxPro, and that the Visual FoxPro environmental variable _SAMPLES points to the sample data correctly.

1. Create a Config.fpw file in a text editor such as Notepad. Add the line MVCOUNT=50500 to the file, and then save the file in your Visual FoxPro home directory. If you already use a Config.fpw file, add this line to the current file.
2. Paste the following code in a program (.prg) file named Test.prg, and then run the program from the Command window:

   LOCAL liCnt AS INTEGER, ;
   	lcMemVar AS STRING, ;
   	lcXLFile AS STRING, ;
   	laDBFArray[1]
   
   CD JUSTPATH(SYS(16))
   CLOSE ALL
   CLEAR ALL
   ERASE Q319277*.*
   
   FOR liCnt = 1 TO 50000
   	lcMemVar = "MVar" + TRANSFORM(liCnt)
   	PUBLIC (lcMemVar)
   NEXT
   
   USE (_SAMPLES) + "\DATA\CUSTOMER"
   AFIELDS(laDBFArray)
   USE IN SELECT("CUSTOMER")
   CREATE CURSOR "XLS_SOURCE" FROM ARRAY laDBFArray
   SELECT "XLS_SOURCE"
   WAIT WINDOW "Building XLS file..." NOWAIT NOCLEAR
   FOR liCnt = 1 TO 500
   	APPEND FROM (_SAMPLES) + "\DATA\CUSTOMER"
   ENDFOR
   COPY TO Q319277_XLS.XLS TYPE XLS
   USE IN SELECT("XLS_SOURCE")
   WAIT WINDOW "Complete!" TIMEOUT 1
   	
   CREATE DATABASE Q319277
   SET DATABASE TO Q319277
   IMPORT FROM Q319277_XLS.XLS TYPE XLS DATABASE "Q319277" NAME ;
   	"Some_Long_Table_Name"
   USE "Some_Long_Table_Name"
   BROWSE
   LIST ALL
   CLOSE ALL
   SET SAFETY OFF
   DELETE DATABASE Q319277 DELETETABLES
   					

   
   
3. Save this file, and then run the program.
