ISLOWER Function

Syntax

Result_Flag as L = ISLOWER(C character)

Arguments

character

A character string.

Description

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

Discussion

ISLOWER() returns TRUE if the first character of the Character_String is lowercase; otherwise, it returns .F. (FALSE). This function is normally used to search fields where case-sensitivity has significant meaning. Use this function in conjunction with the SUBSTR()function to test the second and subsequent characters in a field.

Example

? islower("celtics")
= .T. (TRUE)
' if FIRSTNAME contains "Shirley"
? islower(FIRSTNAME)
= .F. (FALSE)
