The value of the GUI object will be deleted/cleared.

EN.TypeKey( "Name", "${DELETE}" )
EN.TypeKey( "Name", "${DELETE}${SEP}Second Value" )

EN.SetValue( "Name", "${DELETE}" )
EN.SetValue( "Name", "${DELETE}${SEP}Second Value" )

EN.Select( "Artist", "${DELETE}" )
EN.Select( "Artist", "${DELETE}${SEP}Frank Zappa${SEP}Rex Gildo" )

Note: Are values already selected in a GUI object, then these can be cleared with ${DELETE}. These ${DELETE} is specified as the first value:

EN.Select( "Artist", "${DELETE}${SEP}Frank Zappa${SEP}Rex Gildo" )

Technical Note

Deleting the value in the GUI objects is implemented by the GUI Adapter (e.g. SeTextField, SeListBox).

When deleting a GUI object is not possible (for example, selection list does not have the condition $ {EMPTY}), then the GUI property of GUI adapter must be considered.


A OKW-keyword is skipped when ${IGNORE} is entered as a value. This constant is important when re-usable sequences. With this, the activities of the OKW-keywords can be turned off in data-driven test.

EN.Select( "Artist", "${IGNORE}" )
EN.TypeKey( "Artist", "${IGNORE}" )
EN.VerifyValue( "Artist", "${IGNORE}" )

Important: "" (empty string) is equivalent to ${IGNORE}. The following example is equivalent to the previous example.

EN.Select ( "Artist", "" )
EN.TypeKey ( "Artist", "" )
EN.VerifyValue ( "Artist", "" )

${IGNORE} may not be combined with other values. - It will raise an exception and a test case is terminated.

Technical Note

${IGNORE} is evaluated by the OK class. The OKW-Method of a GUI-Adapter (LFC) is not called in this case.


The OKW constant ${EMPTY} is necessary for the "VerifyValue"-keywords:

EN.VerifyValue( "Name", "${EMPTY}" )

Note: VerifyValue( "Name", "" ) ignores the execution of the keyword. In other words, nothing is checked.

Technical Note

The evaluation of ${EMPTY} occurs in the class OK: OK converts ${EMPTY} to "" and compares this with the current value of the GUI object.


${SEP} is used to separate values. E.g. multiple selection in a ListBox.

EN.Select( "Artist" = "Frank Zappa${SEP}Rex Gildo" )

Technical Note

The separation of the values are in the OK class. The values are further processed in the GUI adapters as a list.


${TCS} holds the current test case name.

EN.TestBegin( "This is my first test case" ); // The KeyWord TestBegin() sets TCN="This is my first test case" 
EN.SelectWindow( "MyWindow" );
EN.SetValue( "Comment", "${TCS}" ); // GUI-Object with FN="Comment" is set to "This is my first test case"
EN.VerifyValue( "Comment", "This is my first test case" )
