'default' not allowed in edit control?

running release 14 sp 3.
when i try:
set(control_handle,'String','default')
the string 'default' gets lost somewhere.
however doing any of these works:
set(control_handle,'String','default ')
set(control_handle,'String',' default')
set(control_handle,'String','Default')

Is this a known bug or should i just never try to set the text of an
edit control to 'default'.

Not entirely sure but it appears that default is a key word that
isn't available

why would they be checking the text to be displayed in an edit
control to see if it was a keyword??

it possibly is a key word... but i would not expect that the text to
be displayed in an edit control would be checked to see if it is a
keyword.

if i type in 'default' it does return it properly with the get of the
string property.

Obscure MATLAB trivia.

'default' is a keyword (and the default is ''), so is 'factory'.

You can use '\default' (or '\factory'):

set(control_handle,'String','\default')

Neither. Look at the last section on this page of the documentation:

http://www.mathworks.com/access/hel...s/hg_obj24.html

'default', 'remove', and 'factory' are special keywords when you try to set
a property of a Handle Graphics object to one of those strings. That page
tells you how to set the property to contain that explicit string.

now that is interesting. this is going to be fun since the values i
an filling in could have been typed in by a user and saved in a mat
file in a previous run of the tool i am working on. i know 'default'
will be a common use of one text field, and 'factory' is another
possible use of that field that i hadn't tried yet.

so if i check just before the set command to see if the string is
'default', 'factory', or 'remove' and if so add a backslash before it
then i should be ok.
