2. The values calculated in the financial calculator environment are copied to
the stack with their corresponding tag (identifying label).
Deleting the variables
When you use the financial calculator environment for the first time within the
HOME directory, or any sub-directory, it will generate the variables @@@N@@ @I©YR@
@@PV@@ @@PMT@@ @@PYR@@ @@FV@@ to store the corresponding terms in the calculations..
You can see the contents of these variables by using:
‚@@ @n@@ ‚@I©YR@ ‚@@PV@@ ‚@@PMT@@ ‚@@PYR@@ ‚@@FV@@.
You can either keep these variables for future use, or use the PURGE function
to erase them from your directory. To erase all of the variables at once, if
using ALG mode, try the following:
I@PURGE J „ä
³‚@@@n@@
™ ‚í
³ ‚@I©YR@
™ ‚í
³ ‚@@PV@@
™ ‚í
³ ‚@@PMT@@
™ ‚í
³ ‚@@PYR@@
™ ‚í
³ ‚@@FV@@.
`
The following two screen shots show the PURGE command for purging all the
variables in the directory, and the result after executing the command.
In RPN mode, the command is executed by using:
Enter PURGE, prepare list of variables
Enter name of variable N
Enter a comma
Enter name of variable I%YR
Enter a comma
Enter name of variable PV
Enter a comma
Enter name of variable PMT
Enter a comma
Enter name of variable PYR
