If I wanted to put commands in an array how would I do that if you even can?

I tried it this way

dim lineset1 (3)

lineset1 (0) = line 10,10,200,10
lineset1 (1) = line 10,20,200,20
lineset1 (2) = line 10,30,200,30

print lineset0 (0)
print lineset1(1)
print lineset1 (2)

wait key

If the purpose is just to print the command then yes.

+ Code Snippet

dim lineset1(2) as string

lineset1(0) = "line 10,10,200,10"
lineset1(1) = "line 10,20,200,20"
lineset1(2) = "line 10,30,200,30"

print lineset1(0)
print lineset1(1)
print lineset1(2)

wait key

Unfortunately if you want to utilize the functions in the array then no. you will need to store the parameters in an array and then utilize those parameters.

+ Code Snippet

type t_line
   xPos1 as integer
   yPos1 as integer
   xPos2 as integer
   yPos2 as integer
endtype

dim lineset1(2) as t_line

for i=0 to 2
   read lineset1(i).xPos1
   read lineset1(i).yPos1
   read lineset1(i).xPos2
   read lineset1(i).yPos2
next i

for i=0 to 2
   line lineset1(i).xPos1, lineset1(i).yPos1, lineset1(i).xPos2, lineset1(i).yPos2
next i

wait key

data 10, 10, 200, 10
data 10, 20, 200, 20
data 10, 30, 200, 30

But if I want to use the arrays in a function I could right? as long as they are global, not declared in the function. Or I could declare them in the function then use the function when needed?

The first example did not work the way I wanted the second did.

Is that the most efficient way to do it? What if I wanted to do a screen layout using lines?

Yes. It is my understanding that arrays are always global.

+ Code Snippet

type t_line
   xPos1 as integer
   yPos1 as integer
   xPos2 as integer
   yPos2 as integer
endtype

dim lineset1(2) as t_line

for i=0 to 2
   read lineset1(i).xPos1
   read lineset1(i).yPos1
   read lineset1(i).xPos2
   read lineset1(i).yPos2
next i

DrawLines()

wait key

end

function DrawLines()
   for i=0 to 2
      line lineset1(i).xPos1, lineset1(i).yPos1, lineset1(i).xPos2, lineset1(i).yPos2
   next i
endfunction

data 10, 10, 200, 10
data 10, 20, 200, 20
data 10, 30, 200, 30

You could store the data in data statements as I have done above or read a saved array or read the data from a text file.
