Understand if the font has defined height or 0

[X11start]

In my lisps, when I have to do a (command "Text"... I have always used a font with height 0. If I running my lisp, on drawings that have fonts with defined height ... my "commands" no longer work correctly. Is there a flag or a dxf code to understand if the font I should use has height 0 or defined height?
Practically I would need a value that makes the lisp understand whether to use:

(command "_text" "_mc" pos htxt rot "MY TEXT")

or:

(command "_text" "_mc" pos rot "MY TEXT")

I am guessing you mean the style is set to 0 text height? 0 means you can have different sizes when you create a new mtext or text allowing the use to set 'textsize. if a text style as a set height it will change any text to that size when you set that style.

 

(command "_text" "_mc" pos "" rot "MY TEXT") ;"" uses what ever the variable 'textsize is set to.
(command "_text" "_mc" pos pause rot "MY TEXT") ;pause allows user to input a diffrent text size or enter/right click to accept default.

 

--EDIT--

 

if htxt is set to real or string that option will also work.

Are you referring to text height in text style ?

Something like this

 

(setq ts (cdr (assoc 40 (tblsearch "STYLE" (getvar "TEXTSTYLE")))))
      (if (zerop ts)
           (command "TEXT" "498,18" "3.5" "0" val1)
           (command "TEXT" "498,18" "0" val1)
       )  

 

If use entmake can overwrite text height.

 

(entmakex 
	 (list 
           (cons 0 "TEXT")
           (cons 10  pt)
           (cons 40 hgt)
           (cons 1  str)
	(cons 50 ang)
	(cons 62 col)
	 )
      )

Many thanks for all the answers... and especially to Bigal: it was precisely the variable "TS", which I could not find!
