Syntax: STRPTR(StringVariable)
Typ: Funktion
Kategorie: Pointer

STRPTR gibt einen Pointer zu einer String-Variablen zurück. Es ist ein Alias zu SADD und verweist auf den Anfang des tatsächlichen String-Inhalts, während @ auf den Anfang der Datenstruktur zeigt. Im Artikel zum Datentyp STRING finden Sie nähere Informationen zur Handhabung des Speichers.

Beispiel:

DIM s AS STRING

PRINT STRPTR(s)



s = "hello"

PRINT STRPTR(s)

s = "abcdefg, 1234567, 54321"

PRINT STRPTR(s), @s



POKE UBYTE, STRPTR(s), 65

PRINT s

Ausgabebeispiel:

0

160527952

160527952     3215135288

Abcdefg, 1234567, 54321
