Need help with inventory

[GoliBroda]

These are my inventory codes:

//Create event
empty = "<empty>"
eq[0] = empty
eq[1] = empty
eq[2] = empty
eq[3] = empty
eq[4] = empty
eq[5] = empty
eq[6] = empty
eq[7] = empty
eq[8] = empty
eq[9] = empty
eq[10] = empty
eq[11] = empty
eq[12] = empty
eq[13] = empty
eq[14] = empty
eq[15] = empty
eq[16] = empty
eq[17] = empty
eq[18] = empty

//First page of the eq menu 
if window = 2 && option <= 9 {
draw_text(xinv,yinv[0],eq[0])
draw_text(xinv,yinv[1],eq[1])
draw_text(xinv,yinv[2],eq[2])
draw_text(xinv,yinv[3],eq[3])
draw_text(xinv,yinv[4],eq[4])
draw_text(xinv,yinv[5],eq[5])
draw_text(xinv,yinv[6],eq[6])
draw_text(xinv,yinv[7],eq[7])
draw_text(xinv,yinv[8],eq[8])
draw_text(xinv,yinv[9],eq[9])
}

//second page
if window = 2 && option > 9 {
draw_text(xinv,yinv[10],eq[10])
draw_text(xinv,yinv[11],eq[11])
draw_text(xinv,yinv[12],eq[12])
draw_text(xinv,yinv[13],eq[13])
draw_text(xinv,yinv[14],eq[14])
draw_text(xinv,yinv[15],eq[15])
draw_text(xinv,yinv[16],eq[16])
draw_text(xinv,yinv[17],eq[17])
draw_text(xinv,yinv[18],eq[18])
}

it works well, draws the empty fields of my eq. But it looks awfull, dont you think that?
and when i start writing the codes for collecting items there will be 2x more of this.

Is there way to optimise these codes to few lines of code?

you can use for loops to remove a lot of repeated code.
example:

empty = "<empty>"
for(var i=0; i<max_slots; i++) {
eq[i] = empty;//will set all values to empty
}

and you can do something similar to the draw event but im not sure what the yinv[0] array is for? positioning?
because you can do this for positioning

for(var i=0; i<max_slots; i++) {
draw_text(xinv,yinv+(i*text_height),eq[i]);
}

For initializing, you can backwards initialize it.

empty = "<empty>"
eq[18] = empty;
