Creating and Using Parameters
You can use parameters
to pass data values external to your computation into your computation
script; parameters thus enable you to reuse a given computation with different
sets of external values, in different contexts.
To create a computation variable
that accepts a parameter
- Open the Computation Editor
for the computation you wish to use your parameter in.
- In the Script
tab, click the Add parameter
button located below the name field.
- In the New Parameter dialog, enter a name for the parameter, select
a type of variable the parameter will represent from the drop down
list, and click OK.
- The parameter is now listed in the Parameters section of the Computation
Editor, enabling you to drag and drop the parameter into the script
as necessary.
You can reorder (or remove) a parameter from the Parameters
list by right clicking on a parameter and selecting the operation from
the menu.
To use this computation variable
from another computation or script
- Open the Computation Editor
for the computation from which
you wish to use your computation with parameters.
- In the Components tab of the tools pane, drag and drop your computation with
parameters into the script. HotDocs will automatically generate
placeholders for each of the parameters required by the computation.
- Drag and drop variables or
values to replace the placeholders as you would do when replacing
placeholders for the system expression models.
