IPL has the ability to do arrays. A array is a way of referancing different
areas of data using the same handler name. Each can be refeared to as a
different layer or dimention. IPL has the ability to do up to 3 dementions.
You define the number of dimentions bye doing <type>(#)
example:

 @ str(4)  usrname
 @ byte(4) usrage

This gives you 4 independant strings that can be access from the variable
usrname. These strings can be accessed and written to by doing something
simular to the following.
{
@ str(2) s

 for i = 1 to 4 do {
   cout['Enter name:"]
   s(1) = instr["","n","*","/mn",30]

   usrname(i) = s(1)

   cout['Enter age:"]
   s(2) - instr"","n","n","/mn",2]
   usrage(i) = s(2)
  }

 for i = 1 to 4 do {
   coutln[usrname(i)]
   coutln[usrage(i)]
  }
}

This procedure gives prompts you four times for a name and an age. It then
outputs each back to screen using one only two variables. Using normal
methods this would require eight.
