Build a Loop is the technique to repeate a sequence of instructions a certain number of times based on an initial and limit value and a specified increment.
It is important to declare all the loop variables.
The generic statement is DO/ index variable, initial value, limit value, increment.
$$ Example of a Do Loop
DECL/INTGR,iDECL/CHAR,20,elnmDECL/DOUBLE,xx,yy,zz
$$ This is to create some dummy points.
F(POI_1)=FEAT/POINT,CART, 1.111,2.222,3.333, 0,0,0F(POI_2)=FEAT/POINT,CART, 4.444,5.555,6.666, 0,0,0F(POI_3)=FEAT/POINT,CART, 7.777,8.888,9.999, 0,0,0FA(POI_1)=FEAT/POINT,CART, 1.111,2.222,3.333, 0,0,0FA(POI_2)=FEAT/POINT,CART, 4.444,5.555,6.666, 0,0,0FA(POI_3)=FEAT/POINT,CART, 7.777,8.888,9.999, 0,0,0
$$ DO/ index variable, initial value, limit value, increment
