Some of the work was actually done by Rob Taylor, and when i took over
TI-ROM
a continued the work. Basically Rob Taylor and I found all the rom
version people
are talking about.
So what did Andreas do ? After having found the resize function i did
not really
have time to test it, and i only had acces to one calc. Andreas was kind
enough to
do almost all the testing of the function. Since Andreas was able to
test the function
on more than one rom version we help check out all of them. All in all
andreas was
a big help in finishing the work.
If Andreas Ess gave some the impression that he did all the work on this
i am sure
he did not mean too, he have been working together for so lomg with out
problems.
Some people seem to think that Usgarrd "invented" the variable function,
but in riality
most of them where discovered in 1996, and the rest in 1st quater of
1997. The developers
of Usgarrd got thre information before every one else because they
helped testing
the functions.
Why has the information not been released ? The answer is quite simpel,
lack of time.
I have had too many other prolect to work on, and has therefore not had
the time to
finish ti-rom 1.1. I do not know when it will be released, but it will
hope fully be
before 1st of setember.
Since so many people have shown interest in these functions i have
decided to release
a document which i wrote this spring. It contains the adresses for the
variable function
and should help the people who wants to use them to get started.
ADD.10 is only a part of the info which is going to be released with
tirom 11, but i
hope you guys find it useful.

Additions and corrections to TI-ROM.TXT 1.0.

Input: HL -> VAT entry
DE -> Variable data
Result: The VAT entry and the data space is deleted.

+-------------------+-------+-------+-------+-------+-------+-------+-------+
Input: OP1 hols variable name and name length, A holds type of variable,
HL = # of reals (10 bytes) to allocate.
Result: HL = pointer to VAT entry
DE = pointer to data space
Note: This function does not set the length byte. The 2 bytes needed for the
length byte is added to the # of bytes needed. This function calls the
error handler in case of an error.
+- Allocate memory -+-------+-------+-------+-------+-------+-------+-------+
| | 29A7 | 29AB | 29AB | 29AB | 29AF | 295A | 2974 |
+-------------------+-------+-------+-------+-------+-------+-------+-------+
Input: OP1 hols variable name and name length, A holds type of variable,
HL = # of bytes to allocate
Result: HL = pointer to VAT entry
DE = pointer to data space
Note: This function does not set the length byte. The two bytes need for the
length field of some var types is not added to the # of bytes needed.
To have these bytes added call 6 bytes before (29A1 for 3.0A). This
function calls the error handler in case of an error.
+- Resize variable -+-------+-------+-------+-------+-------+-------+-------+
| | 2AB0 | 2AB4 | 2AB4 | 2AB4 | 2AB8 | 2A63 | 2A7D |
+-------------------+-------+-------+-------+-------+-------+-------+-------+
Input : HL = current size of variable. DE = new size of variable.
(80D0) and (80D2) -> variable. OP1 holds variable info.
Result : The variables size is adjusted to the new size.
Note: This function has not been tested in anyway !
Besides the above function the rom contains a list of functions to allocate
memory for a specific var type. these function are listed below. All the
rutines below places the correct value in the data length field, if that is
needed for that var type.
