You can specify additional characteristics of string1 by using the operands PREFIX, SUFFIX, CHARS, and WORD. You can abbreviate PREFIX, SUFFIX, and CHARS to PRE, SUF, and CHAR, respectively.

CHARS

Locates string1 anywhere the characters match. This is the default.

PREFIX

Locates string1 at the beginning of a word.

SUFFIX

Locates string1 at the end of a word.

WORD

string1 is delimited on both sides by blanks or other non-alphanumeric characters.

In this example, the editor would find the highlighted strings only:

CHARS 'DO'  - DO DONE ADO ADOPT 'DO' +ADO (DONE) ADO-

PREFIX 'DO' - DO DONE ADO ADOPT 'DO' +ADO (DONE) ADO-

SUFFIX 'DO' - DO DONE ADO ADOPT 'DO' +ADO (DONE) ADO-

WORD 'DO'   - DO DONE ADO ADOPT 'DO' +ADO (DONE) ADO-

If you do not specify an operand, the default is CHARS.
