Suggested solution for a large volume input data (translated into English by I.Krupnik)
When working with Mathcad sheet opened in MAS or even in Mathcad shell some difficulty appears if a large volume information has to be dealt with, as in a case of repetitious calculations with varying data where the user has to examine and if necessary change the values of tens of text windows before activating the Recalculate key -an example is given at the address http://twt.mpei.ac.ru/mas/worksheets/Exp_Steam_K_300_240_LMZ.mcd
Using
the regular (Web) Controls for this purpose is very cumbersome.
When using shell Mathcad this problem can be resolved by
creating at input file in the disk and by using the readprn function (or such) to read the
information into the Mathcad files. But it is
too difficult to do if using MAS technology, so we recommend a different way to
deal with it.
Fig 2.20
New
input data presented as electronic tables(see fig.2.20)
should be prepared primary to starting MAS (again this data might be a
corrected input information from a previous MAS use saved in the user archive).
By a simple copying (Ctrl+Insert – Shift+Insert) this data can be brought into “long “ Text box
WebControl of the Mathcad work sheet opened from the Web (see, for example
fig.2.5 and 2.6) – one or several text windows if the chain to be copied
exceeds 256 symbols. The button (from the WebControls panel)
or Enter (from the keyboard) have to be activated which will initiate the
calculations with the new input data. And again if the result is also of
large volume, it can be output not as separate scalar values but as a table
which can also be copied from the Web Mathcad sheet into the user worksheet for
a further analysis and development.
This suggested solution of the problem in archiving and input
of the large volume data into the WebSheet has desirably to be built-in into
MAS and the author has informed the developers on this part (see point 15 in
the “MAS content” attachment ).Most non-Web
calculation programs-Windows applications – have in their File Menu the
special commands New [Project], Open
[Project], Save [Project]. These application-attachments allow to work with the
input archive –see fig 2.21 where these commands are shown (the menus and
dialogue windows of one attachment of Windows program with the title of the
calculation of water preparation installation where the data of the separate
projects (different stages of using the program) are saved on a file disk with
the names Sample1.rod, Sample2.rod,.......Sample8.rod
