If you only need to output the text, you don't need to used READ_TEXT like in an ABAP program, 
just use the INCLUDE command in SAPScript. 

It will read the text and output it to your form. 

The Syntax is like this: 

/: INCLUDE &T166K-TXNAM& OBJECT &T166K-TDOBJECT& ID &T166K-TDID& LANGUAGE &EKKO-SPRAS&
