choosing what text to display in drawing

[JeniaL]

i want to enhance my title block macro by choosing what text to display while macro is running.
for example i need a message that let me choose one of two options for general units

choose units: DIMENSIONS:MM[INCH] or DIMENSIONS:INCH[MM]
GENERAL TOLERANCES: GENERAL TOLERANCES:

now it looks like this
CreateTextAF Text_34,GetOH() + .985*Col(1)+1 ,GetOV() + 0.98*Row(4)-13 ,"TitleBlock_Text_DIMENSIONS" ,catTopLeft ,1.2

BTW how can i edit an existing thread?
