FOR f[(len,edit)] FROM exp TO exp [STEP exp] DO label
 - A loop that runs from a value to a value. Built in edits are supported. If a STEP value is not supplied, filePro will determine a STEP value based on the FROM and TO expression values. A FROM value that is less than a TO value will result in a positive STEP ("1"). If FROM is greater than TO the STEP value will be negative ("-1"). Each iteration of the loop will update the value of "f", incrementing by STEP, and goto the label specified by DO.

Note: The FROM, TO, and STEP expressions are evaluated once when the loop is first executed. Changing these values once the loop starts executing will not change how the loop run.

      Then: FOR f(10,.0) FROM "1" TO "10" STEP "1" DO lp1; goto en1 
  lp1   If: 
      Then: msgbox f    ' print the value of "f" from 1 to 10
      Then: end
  en1   If:
      Then: FOR d(10,mdyy/) FROM "12/01/2024" TO "12/31/2024" DO lp2; goto en2
  lp2   If:
      Then: msgbox d    ' print the value of "d" from 12/01/2024 to 12/31/2024
      Then: end
  en2   If:
      Then: end
	

WHILE cnd DO label
 - A loop that runs while the condition is true. Each iteration checks the condition (cnd) and while the value is true goes to the label specified by DO. A condition can be an IF expression or label.

      Then: declare total(10,.0)
      Then: total="0"
      Then: lookup inv=invoice r=(rec) -nx
      Then: WHILE inv DO lp1; goto en1
  lp1   If: 
      Then: total=total+inv(1)
      Then: getnext inv
      Then: end
  en1   If:
      Then: close inv; end
	

LOOP label WHILE cnd
LOOP label UNTIL cnd
 - A loop that runs while the condition is true (WHILE) or until the condition is true (UNTIL). Each iteration starts by going to the label specified by DO, then the condition is checked and the loop either continues or terminates based on the value of the condition. A condition can be an IF expression or label.

      Then: i(10,.0)="10"
      Then: LOOP lp1 WHILE i gt "0"; goto en1
  lp1   If: 
      Then: i=i-"1";
      Then: end
  en1   If:
      Then: end
