1. THE SYS(9025) FUNCTION:

     SYS(9025) - Enables or disables creating the private variable in the TEXT ... ENDTEXT command automatically

     Enables or disables creating the private variable in the TEXT ... ENDTEXT command automatically.

     SYS(9025 [, 0 | 1])

     Parameters
     0
     Disables creating the private variable in the TEXT ... ENDTEXT command automatically.
     1
     Enables creating the private variable in the TEXT ... ENDTEXT command automatically. 1 is the startup default for Visual FoxPro Advanced.

     Return Value
     Character

     Remarks
     TEXT ... ENDTEXT Command (from dv_foxhelp9.chm).

     Sends lines of text specified by TextLines to the current output device or memory variable.
     Visual FoxPro sends lines of text to the current output device until it encounters an ENDTEXT statement or until the program ends.

     The current output device can include the main Visual FoxPro window, a user-defined window, a printer, a text file, or a low-level file.
     TEXT [TO VarName [ADDITIVE] [TEXTMERGE] [NOSHOW] [FLAGS nValue] [PRETEXT eExpression]]
     TextLines
     ENDTEXT

     TO VarName
     Specifies the memory variable name to use for passing the contents of the TEXT...ENDTEXT. This variable can already exist.
     If we enable creating the private variable in the TEXT ... ENDTEXT command automatically and the variable doesn't exist,
     Visual FoxPro automatically creates it as a private variable.
     If we disable creating the private variable in the TEXT ... ENDTEXT command automatically and the variable has not yet been declared,
     Visual FoxPro automatically creates it as a private variable.
     The TO clause operates regardless of how SET TEXTMERGE is set. If SET TEXTMERGE is set to a file, and the TO statement is included,
     Visual FoxPro outputs both the file and variable.


2. CAUSE:

     There are some BUGs in the following code.


3. RESOLUTION:

     We can write some code to fix the BUG.
