TOMAS is a single system on the market that enables the user to use any type of formulas for various calculations. In other words, TOMAS accepts external knowledge and uses it in data operations.
Formulas are used in TOMAS for calculation of:
Structural formulas have the following content:
code description
XXX E1,E2,E3,E4,E5,
! 
!
!_ price elements
!_ structural formula code
Calculative formulas have the following content:
code description
E5 (E1+E2)*E3/E4=
!
...........................
!
!_ how E5 is to be calculated, using other price elements
!_ price element code
In general, the content formulas is the following:
G A,C,D,@E,F,
A A= to be taken from price register
C $A= A is corrected by % or amount registered in commercial conditions
D #K*A/100= K= VALUE in product characteristic "K".
E to be taken from a constant (type = VRIJ, code = E)
F A+CD*E= any combination of previous price elements.
Effects of using formulas in TOMAS are the following:
