Doloop command

Doloop command
	*COMMANDS

The DOLOOP command allows statements to be executed a defined number of times with an incrementing variable. The loop will always be executed at least once since the loop-count variable will be incremented at the end of each loop. This variable, if omitted, is an automatically created word named LOOP. The variable may be used freely within the loop,

Example

DOLOOP LOOP1  FROM 1  TO 8  STEP 2
    {
      ...
    NEWWORD = POSITION * LOOP1
    INC NEWWORD POSSPEC
      ...
    }

will execute the commands within curly braces for values of the word LOOP1 of 1,3,5 and 7.

Example

The loop values may be negative ...

DOLOOP  INDEX FROM 7  TO -2  STEP -3

will execute the contained commands for values of the variable INDEX of 7,4,1 and -2.

Example

To exit from a loop before the loop variable has reached the final loop value the IF...GOTO command should be used ...

DOLOOP  FROM X1  TO X2  STEP I  {
      ...
    IF ...
        GOTO ABCD
          ...
   }
LABEL ABCD:
     ...
