how to make the autolisp to affect already selected object

[holyhexor0o0]

Hello everyone, I found this nifty autolisp that can align text to a point from the left/right/middle

however it could not affect already selected objects - meaning the user could only select objects after applying the effect

i actually tried with ssget "P" or "I" or clear previous selection but no luck, thanks in advance

ssget is affecting already selected objects. So it should work already.
Tried it for the first function and it worked.

check if variable 'pickfirst' is set to 1. if it is then command should work on preselected objects.

It already is on, but it still doesn't work on preselected 😄

[komondormrex · Accepted solution]

it is command 'undo' that overthrows the preselected set.

replace it with 

(vla-startundomark (vla-get-activedocument (vlax-get-acad-object)))

and 

(vla-endundomark (vla-get-activedocument (vlax-get-acad-object)))

respectively.
