The value returned for the parameter of function is the string value representing the parameter string associated with the specified object; for example:

 

cyan graphical region Delete size 80 25

    at position 50 10 in ActionBar

    parameter is "Deletepull"

 

response to line "to Delete" from Host

    make parameter of Delete visible

 

If you specify the parameter of function for an object for which no parameter has been defined, the value returned is the null string. When an object is defined, the default value for the parameter attribute is the null string.

 

Be careful not to confuse the parameter of function with the parameter function. The parameter function is a response inquiry, returning the parameter string associated with the object that stimulated the current response. (See Using Response Inquiry Built-in Functions for details on the use of the parameter function.)
