getIndexOf()

getIndexOf() is used to return an integer number which identifies the position of a specified sub-string:

String_var.GetIndexOf(substring, position)

The method needs two arguments:

substring	specifies a quoted string or a variable containing the sub-string that will be searched for
position	is an integer value indicating the position in the buffer string at which the search should begin

To start the search from the very beginning of the buffer string, specify the position argument as 1. This extract of a source code will return 5:

DEFINE pos INTEGER

CALL string_val.Append("a23456789b")

LET pos = string_val.GetIndexof("567",1)

DISPLAY "567 starts from the ", pos, " position"
