  • tExpression

If tExpression contains only a date, Visual FoxPro adds the default time of midnight (12:00:00 A.M.) to tExpression.

  • 2
    Specifies that TTOC( ) return a Character string consisting of only the time portion of the DateTime expression. The settings of SET SECONDS and SET DATE specify if the seconds portion of the time is included in the character string.

Example

The following example creates a Datetime type variable named gtDtime. TYPE( ) displays T, indicating the variable is a Datetime type. TTOC( ) is used to convert the variable to a character type, and TYPE( ) now displays C, indicating the variable is a character type after the conversion.

STORE DATETIME( ) TO gtDtime  && Creates a Datetime type memory variable
CLEAR
? "gtDtime is type: "  
?? TYPE('gtDtime')  && Displays T, Datetime type value

gtDtime = TTOC(gtDtime)     &&  Converts gtDtime to a character value
? "gtDtime is now type: "  
?? TYPE('gtDtime')  && Displays C, character type value
