syntax:!positionof [``type''] ``s'' in ``string''
mean:Reports the positions of the object ``s'' in ``string''. <br/>\
``type'' can be <span class="tt">char</span>, <span class="tt">word</span>, <span class="tt">item</span> or\
<span class="tt">line</span>. If it is specified, then the comparison only takes place for\
corresponding objects of ``string'' which are identical to ``s''. <br/>\
The output of the command is a
list of positions
(char
, word
, item or\
line, according to the value of ``type'') where ``s'' is found in ``string''. <br/>\
If ``type'' is missing, then ``s'' is searched in ``string'' as a substring,\
and the positions reported are character positions.
