[ statements ]
[ statements ]
| statements | The Template statements to execute each time. |
| #BREAK | Terminates the loop. |
| #END | The #LOOP structure terminator. |
The #LOOP structure iterates, executing the statements each time through the loop until a #BREAK statement executes. If there is no #BREAK then #LOOP iterates infinitely.
Example:
// This script creates a set attribute definition of the 1st 10
// natural numbers and defines an attribute named "Set10"
#DECLARE (SetString)
#DECLARE (Ndx)
#SET (SetString, '['); //initialize SetString to [
#SET (Ndx, 1); //initialize Ndx to 1
#LOOP
#IF (%Ndx% > 9) //if we've iterated 9 times
#BREAK // break out of the loop
#ELSE //otherwise
#APPEND (SetString, %'Ndx'% + ',');
//append Ndx and comma to SetString
#SET (Ndx, %Ndx% + 1)
//and increment the value of Ndx
#END
#END
#APPEND (SetString, %'Ndx'% + ']'); //add 10th element and closing ]
EXPORT Set10 := %'SetString'%; //generate the ECL code
// This generates:
// EXPORT Set10 := [1,2,3,4,5,6,7,8,9,10];
