| ### 6.3.4 Usage of commas In SINGULAR, a comma separates list elements and the value of a comma expression is a list. Hence, commas cannot be used to combine several expressions into a single expression. For example, instead of writing
    for (i=1, j=5; i<5 || j<10; i++, j++) {...} // WRONG!!!!!!
one has to write
    for (i,j = 1,5; i<5 || j<10; i++, j++) {...}
