Comments in Mathcad Worksheets

Mathcad 14 and 15 enable us to develop an expression and substitute numerical values of the variables, see Fig. 6.61. 

Many users of Mathcad do not insert the comments to the worksheets thinking that they are created for personal use and elucidative fragments could be inserted later. Often this later never occurs all non-comments (mathematical operators) are inserted into the worksheet, it works and gives precise result there is no time to insert comments, we should go further to develop this worksheet or to create the new one. Still, if the worksheet is intended for personal use some comments in it will not be superfluous. We may tangle even in our own worksheet opening it after a time if it has no comment, for example a name. 

Comment. We can name the operator non-comment if the computation interrupts and displays an error message when it being withdrawn from the worksheet. 

Returning to the point of Sect. 6.2 we can contend that the best comments are right, indicating names of variables and functions were fixed long ago on the definite quantity in a definite branch of science. It wUl be enough to name such a worksheet and that will be clear without comments. 

Comment. A name and other data concerning a worksheet (the time of creation etc) can be placed in the heading and the basement of a worksheet by the command Header and Footer... from the View menu. Mathcad 12-15 provide advanced features to save metadata (information about information).
