Get functions 111

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 6, 12):

ScriptParameter = "a = 5; b = 10"

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

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

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

Get(ScriptResult)

Format

Get(ScriptResult)

Parameter

None

Data type returned

text, number, date, time, timestamp, container

Description

When this function is part of a calculation evaluated within a script, 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.

Example

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
