ISUPPER Function

Syntax

Result_Flag as L = ISUPPER(C character)

Arguments

character: A character string.

Description

Returns TRUE if the first character of a string is uppercase.

Discussion

ISUPPER() returns .T. (TRUE) if the first character of the Character_String is uppercase; otherwise, it returns .F. (FALSE). This function is normally used to search fields where case-sensitivity has significant meaning.

Example

? isupper("Celtics")
= .T.
' if FIRSTNAME contains "Shirley"
? isupper(FIRSTNAME)
= .T.
