[5.9] Graphlink Software Sends Either Ti-89 Or Ti-92 Plus Files - Texas Instruments TI-89 Tip List

This is the program tstr(), which is used to save the converted string to l2.
tstr()
Prgm
"???"→l2
EndPrgm
This is strcompr(), which compares the two strings:
strcompr(α,β)
Func
©Compare strings α, β; return differences as character codes
©1jan2002/dburkett@infinet.com
Local k,res,c
if dim(α)≠dim(β):return "dim error"
{}→res
For k,1,dim(α)
if mid(α,k,1)=mid(β,k,1) then
{0}→c
else
{ord(mid(β,k,1))}→c
endif
augment(res,c)→res
EndFor
return res
EndFunc
strcompr() returns a list with one integer for each character in the strings. If the corresponding
characters are the same, zero is returned. If the characters differ, the character code for string l2 is
returned. For the example I'm using, this call
strcompr(l1,l2)
returns {63,63,63}, indicating that none of the converted string characters match the original
characters, and they have all been converted to char(63), which is "?".

[5.9] GraphLink software sends either TI-89 or TI-92 Plus files

There are two versions of TI's GraphLink software, one for the TI-89 and one for the TI-92 Plus. By
default, the Link Send dialog box shows only the file types for that particular calculator model, for
example, GraphLink for the TI-92 Plus shows only file types of .9x*. However, you can send TI-89 files
to a TI-92 Plus, and vice versa, by one of these methods with either GraphLink software version:
1. Type the file name directly in the File Name text box, if you know the name. Include the file
type suffix.
2. In the List Files of Type drop-down menu, choose All Files (*.*), then choose the desired file.
3. In the File Name text box, type *.89* to list all TI-89 files, or type *.9x* to list all TI-92 Plus files.
Some programs and functions are specific to the particular calculator model, but most functions and
programs will run on either model. The file suffix is assigned when the programmer saves the file, so
files saved from GraphLink for the TI-89 will have a .89* suffix by default.
