Description
User Doubles can be used to transfer information between the host and resident controller programs. The 32 register array of double precision floating point numbers can be read and written from both sides. There is no established convention for how the doubles are used. Generally they provide parameters to resident controller routines and return results back User Double 1 contains the value "e" (2.71828) as a diagnostic aid to check register alignment and confirm that the word order is correct between the controller and the host.
Escapes
Reading and writing User Double registers does not generate any exceptions.
Examples
Assign the value 356.2 to user double 5.
Write_Double(System_+_UserDouble5_d,356.2);
Read the value in user double 31.
Show_Number(Read_Double(System_+_UserDouble31_d);
