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

That looks to me like the same as above? I'm not sure what you changed?

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.
