Character's usage for parameter callbacks doesn't allow using the | character inside a string : It can be a bug on Matlab 7.8 (R2009a)?

Hello everyone,
I'm working on a masked block, when I try to associate this command to a mask parameter callback http://www.mathworks.nl/help/toolbox/simulink/slref/f23-18517.html
set_param(gcb,'MaskPromptString','Ninputs|Summary|Toggle to negative sign the input IN1?|Toggle to negative sign the input IN2?|')
and click on apply. I have this popping up error message shows up:
for mask parameter 1 contains a '|' character, which conflicts with the character's usage as a delimiter between mask callbacks. Replace the boolean expression containing the '|' character with a matlab 'or' command e.g. 'a|b' with 'or(a,b)'
And that is very weird because I'm not doing any logical operation. Is that a bug? Do you know if it's possible to overcome this problem or if I can achieve my aim, in a different way?
I saw the MaskPropmts parameter but I'm very confused about how to use the cell variable
thanks 4 reading
a good day

finally guys I wrote this code
set_param(gcb,'MaskPromptString','Ninputs|Summary|Toggle to negative sign the input IN1?|Toggle to negative sign the input IN2?|')
I put this code within a m file call it in the dialog callback
it looks like it's working
I'm going to test it

I just wrote this code inside a m file then I made a reference to it inside the dialog callback
set_param(gcb,'MaskPromptString','Ninputs|Summary|Toggle to negative sign the input IN1?|Toggle to negative sign the input IN2?|')
before, this code was directly inside the dialog callback.
