Insert blocks at XYZ coordinates and x-, y- and z-scales from ASCII

I found this LISP code that can insert a block at coordinates from an ASCII.

(defun c:universal( / file f a osmode);PointsToBlocks
(while (not file)
(setq file (getfiled "Input file" "coords" "txt" 4))
)
(setq f (open file "r")
osmode (getvar "OSMODE")
)
(setvar "OSMODE" 0)
(while (setq a (read-line f))
(command "._insert" "block1" a 1 1 0)
)
(setvar "OSMODE" osmode)
(princ)

What I want to be able to do is insert blocks from an ASCII and also set the x-, y-, and z-scales.

For example, I have these lines in ASCII, the data points refer to X position, Y position, Z position, X scale, Y scale, and Z scale.

Thank you in advance for your help, I am a beginner.
