SUBSTR( ) Function
Returns a character string from the given character expression or memo field, starting at a specified position in the character expression or memo field and continuing for a specified number of characters.
Specifies the character expression or memo field from which the character string is returned.
Specifies the position in the character expression or memo field cExpression from where the character string is returned. The first character of cExpression is position 1.
If nStartPosition is greater than the number of characters in cExpression, SUBSTR( ) returns an empty string ("").
Specifies the number of characters to return from cExpression. If you omit nCharactersReturned, characters are returned until the end of the character expression is reached.
The following example stores string 'abcdefghijklm' to the variable myString using the STORE command. CLEAR clears the main Visual FoxPro window. Beginning with the first character as specified by nStartPosition = 1, SUBSTR( ) displays the string 'abcde' with five characters as specified by nCharactersReturned = 5. SUBSTR( ) then displays the string 'fghijklm' beginning with the sixth character in the string as specified by nStartPosition = 6 until the end of the character expression is reached as specified by the omission of a value for nCharactersReturned.
