Evaluate("Let ( [" & Get(ScriptParameter) & "]; a + 1 & \", \" & b 
+ 2 )" )
The following example shows how to pass named parameters, while keeping the ability to 
check the syntax of the second parameter of the Let function (the example returns 

 

):

ScriptParameter = "a = 5; b = 10"
Let(  [a = Evaluate("Let( [" & Get(ScriptParameter) & "]; a )"), 

b = Evaluate("Let( [" & Get(ScriptParameter) & "]; b )")]; 

a + 1 & ", " & b + 2 )

Get(ScriptResult)

None

text, number, date, time, timestamp, container

When this function is part of a calculation evaluated within a 

, returns the script result 

from a performed subscript. If a subscript doesn’t return a result, then the content of the 
script result will be empty.

In the following example, script Find Customers returns the results of a find request when 
it is called from script Do Reports. Script Find Customers uses the optional script result of 
the Exit Script script step. Script Do Reports then uses Get(ScriptResult) to determine 
what other script steps should be performed based on the returned result stored in 
Get(ScriptResult).
Find Customers

Set Error Capture [On] 
Perform Find [Restore] 
New Record/Request 
Exit Script [Result: Get(FoundCount) < 10]
Do Reports

Perform Script [Find Customers] 
If [Get(ScriptResult) = 0] 

Show Custom Dialog [“You have created 10 records already.”] 

End If
