WHILE

 

 Repeat statements an indefinite number of times.

  The general form of a WHILE statement is:

 

 

     WHILE variable, statement, ..., statement, ENDMNZCU2

 

 

  The statements are executed while the variable has all

  non-zero elements. The variable is usually the result of

  expr rop expr where rop is ==, <, >, <=, >=, or ~=.

  For example (assuming A already defined):

 

 

          E = 0*A; F = E + EYEMO0DU2(E); N = 1;

          WHILE NORM3BIWKE7(E+F-E,1) > 0,

             E = E + F;

             F = A*F/N;

             N = N + 1;

          ENDMNZCU2
