• Description:
    Via these keywords you can stop or start loops earlier. These keywords can be used in LOOP, IF, WHILE, REPEAT, SELECT and FOR loops.

  • News:
    • From 0.16
      • NEXTIF and NEXTIFN keywords added


  • Syntax: 
      EXITIF <exp> [ DO <statements> ] [ ( IS / GIVES / GIVING / RETURNING ) <list> ]

    While <exp> is FALSE nothing happens, if TRUE, <statements> will be processed and <list> of values will be returned. You can also use EXITIFN keyword to negate the <exp>.
      NEXTIF <exp> [ DO <statements> ]

    While <exp> is FALSE nothing happens, if TRUE, <statements> will be processed and loop will continue from the beginning, that means, that the rest of code between this NEXTIF and ENDWHILE/ENDLOOP/etc will be skipped and the loop will continue. You can also use NEXTIFN keyword to negate the <exp>.

  • EXIT keyword: 
      EXIT [ DO <statements> ] [ ( IS / GIVES / GIVING / RETURNING ) <list> ]

    EXIT keyword is multiple-line equivalent for single-line IS keyword. It is quite useless for loops (LOOP, WHILE, REPEAT, FOR), but it is very useful for SELECT and IF statements. It allows you to return a value from the statement. Watch returning values: IF, SELECT.

  • Note:
    GIVES, GIVING and RETURNING keywords are all the same as IS keyword, it is alloved only to be more readable.
