I'm creating a text file as shown below. Most of the file will
be not change, but at one point in the file I want to insert
some text which is specific to the instance it was run.

Anyone know how to do this?

iHandle = FCREATE("TestMenu.prg")
_TEXT = iHandle

TEXT TO _TEXT NOSHOW

. Bunch of text here
. Bunch of text here

ENDTEXT
=FCLOSE(iHandle)
