[Gambas-user] Split: misleading Wiki

[d4t4full at ...626...]

Matti

Your string has 3 substrings when split with SPLIT (STRING, "#"):

Index 0: "Hello"
Index 1: ""
Index 2: "12345"

It is documented that separators are single characters, not strings; you can specify a string because any of its individual characters may be used as separator.

If you also specify IgnoreVoids as True, split should omit the null string and return only:

Index 0: "Hello"
Index 1: "12345"

HTH,
