The following example creates a text string, then outputs the TEXTMERGE of that function.

TEXT to myvar noshow &&textm 
   this is a test   <<datetime()>>
   <<program(-1)>>
   <<myvar>>
   textmerge(myvar) (this line is literal)
   <<doit(myvar)>>   (cause recursion
   END of orig text
endtext
?myvar
?"Now starting textmerge"
?textmerge(myvar)

PROCEDURE doit(myvar)
*  r=i   && cause an error
   if program(-1) > 3
