sequence
(control module) -- evaluates a series of patches
Syntax
sequence patch &rest oppatch
Inputs
| name | data type(s) | comments |
|---|---|---|
| patch | any | |
| oppatch | any | repeatable; additional patches to evaluate |
Output

first| any| the results of the first patch
second| any| sequence has as many outputs as inputs, each output returning
the results of the corresponding input
Description
sequence is used when you need to evaluate a series of patches one after the other. You can add as many inputs as you like; outputs will be created at the same time. When used, the patches or functions connected are evaluated in order from left to right. Even if nothing is connected to some outputs, all the inputs will be evaluated.
Examples
Using sequence to bind and evaluate a variable
Here, the LISP function setf is used to bind the value 10 to the variable variable-n at the first input. The second input takes the function om+ , which adds the value of variable-n (evaluated with the function eval ) to
- The second output of sequence will return:
? OM->17
Note that both patches were evaluated (or else the answer would not have been 17 since the number 10 would not have been assigned to variable-n ) even though we only took the value of the second input.
