For text string building I am very fond of php’s interpolate feature:
# my variable
$name = "Joe Bob";
# my command
$my_sentence = "Hello {$name}!";
In 4D the same can be accomplished with text objects.
`have a table [Table]full_name ` this is the typed string for the text ` notice the "<" and ">" enclosing the field reference vt_object:="Hello <[Table]full_name>!" ` outputs "Hello Joe Bob!" assuming that was what was loaded in the record
