Mask Parameters

• The prompt, which you enter in the Prompt field
• The variable that holds the parameter value, which you enter in the Variable field
• The type of field created, which you specify by selecting a Control type
• Whether the value entered in the field is to be evaluated or stored as a literal, which you specify by selecting an Assignment type

• The Prompt field values for all dialog box parameters are stored in the MaskPromptString parameter as a string, with individual values separated by a vertical bar (|), as shown in this example.

  "Slope:|Intercept:"
  

• The Variable field values for all dialog box parameters are stored in the MaskVariables parameter as a string, with individual assignments separated by a semi-colon. A sequence number indicates which prompt is associated with a variable. A special character preceding the sequence number indicates the Assignment type: @ indicates Evaluate, & indicates Literal.

For example, "a=@1;b=&2;" indicates that the value entered in the first parameter field is assigned to variable a and is evaluated in MATLAB before assignment, and the value entered in the second field is assigned to variable b and is stored as a literal, which means that its value is the string entered in the dialog box.

• The Control type field values for all dialog box parameters are stored in the MaskStyleString parameter as a string, with individual values separated by a comma. The Popup strings values appear after the popup type, as shown in this example:

  "edit,checkbox,popup(red|blue|green)"
  

• The parameter values are stored in the MaskValueString mask parameter as a string, with individual values separated by a vertical bar. The order of the values is the same as the order the parameters appear on the dialog box. For example, these statements define values for the parameter field prompts and the values for those parameters.

  MaskPromptString     "Slope:|Intercept:"
  MaskValueString      "2|5"
