SET MACRO PARAMETER
SET MACRO PARAMETER ( selector ; textParam )
| Parameter | Type | Description | |
|---|---|---|---|
| selector | Integer | → | Selection to use |
| textParam | Text | → | Text sent |
This command is not thread-safe, it cannot be used in preemptive code.
Description
The SET MACRO PARAMETER command inserts the paramText text into the method from which it has been called.
If text has been selected in the method, the selector parameter can be used to set whether the paramText text must replace all of the method text or only the selected text. In selector, you can pass one of the following constants, added to the “4D Environment” theme:
| Constant | Type | Value |
|---|---|---|
| Full method text | Longint | 1 |
| Highlighted method text | Longint | 2 |
If no text has been selected, paramText is inserted into the method.
Note
In order for the GET MACRO PARAMETER and SET MACRO PARAMETER commands to work correctly, the new “version” attribute must be declared in the macro itself. The “version” attribute must be declared as follows:
<macro name="MyMacro" version="2">
--- Text of macro ---
</macro>
Example
This macro builds a new text that will be returned to the calling method:
var $input_text : Text
var $output_text : Text
GET MACRO PARAMETER(Highlighted method text;$input_text)
//Suppose that the selected text is a table, i.e. “[Customers]”
$output_text:=""
$output_text:=$output_text+Command name(47)+"("+$input_text+")" // Select all ([Customers])
$output_text:=$output_text+"$i:="+Command name(76)+"("+$input_text+")" // $i:=Records in selection([Customers])
SET MACRO PARAMETER(Highlighted method text;$output_text)
//Replaces the selected text by the new code
