Description

SearchBuf searches the buffer Buf for the occurrence of SearchString. At must Buflen characters are searched, and the search is started at SelStart+SelLength. If a match is found, a pointer to the position of the match is returned. The parameter Options specifies how the search is conducted. It is a set of the following options:

Option	Effect
soDown	Searches forward, starting at the end of the selection. Default is searching up
soMatchCase	Observe case when searching. Default is to ignore case.
soWholeWord	Match only whole words. Default also returns parts of words

The standard constant WordDelimiters is used to mark the boundaries of words.

The SelStart parameter is zero based.

Errors

Buflen must be the real length of the string, no checking on this is performed.
