The SOLVR sub-menu

The SOLVR sub-menu in the TVM sub-menu will launch the solver for solving

TVM problems. For example, pressing @)SOLVR, at this point, will trigger the

following screen:

As an exercise, try using the values n = 10, I%YR = 5.6, PV = 10000, and FV

= 0, and enter „[ PMT ] to find PMT = -1021.08…. Pressing L,

produces the following screen:

Press J to exit the SOLVR environment. Find your way back to the TVM

sub-menu within the SOLVE sub-menu to try the other functions available.

Function TVMROOT

This function requires as argument the name of one of the variables in the

TVM problem. The function returns the solution for that variable, given that

the other variables exist and have values stored previously. For example,

having solved a TVM problem above, we can solve for, say, ‘N’, as follows:

[ ‘ ] ~n` @TVMRO. The result is 10.

Function AMORT

This function takes a value representing a period of payment (between 0 and

n) and returns the principal, interest, and balance for the values currently

stored in the TVM variables. For example, with the data used earlier, if we

activate function AMORT for a value of 10, we get:

1 2 ... 228 229 230 231 232 233 234 235 236 237 238 ... 863 864
