function ExtractWordPos( |

):string; |
N |
|
Which word to extract |
S |
|
String to extract a word from. |
WordDelims |
|
Characters to use as word delimiters |
Pos |
|
On return, contains the position of the N-th word. |
N-th word of the string, or empty if N is out of range.
ExtractWordPos extracts the N-th word from the string S and returns the position of this word in Pos. The set of characters in WordDelims are used to mark word boundaries. A word is defined as any non-empty sequence of characters which are not present in WordDelims : if a character is not in WordDelims , it is considered as part of a word. If an N -th word cannot be found, an empty string is returned and Pos is zero.
Unlike ExtractDelimited, an empty string is not a valid return value, i.e. is not a word. If an empty string is returned, the index N was out of range.
The pre-defined constant StdWordDelims can be used for the WordDelims argument.
None.
