backup objects

[francisco guzman]

Hello guys, I have an hp49g rom 16, I am able to beate a backup object say a
backup of a library as follows:
"::
CK1
OB>BAKcode
;
@"

My question is how do i undothis and get back the original library?
I tried the following but it does not work:
"::
CK1
BAK>OB
;
@"
Any ideas?

Why don't you work with Library data's instead? Do you really need the
backup objects?

Hello,

As a HP48Gx user, i have the same problem;
In order to work with max mem available, all my program were stored in port and
was call like ( alias for mac - << :port:program RCL and EVAL >> ). To speed up
program execution I've plan to use direct access memory in SysRpl for recalling
and executing program ... but i(ve got the same problem ... and other work to do
...

Hello,

Well, I have been lookin in the ROM for a BAK>OB function, and haven't found
it (maybe I should have spent more time trying). I think it's the case,
because originaly, they were no need to do so. Backup obejct had to be
created in order to be stored in port (this is not needed anymore as it is
done on the fly on the HP49), but then, the RCL was doing the recal of the
content of the object directly, so BAK>OB was not needed.

To solve your immediat problem, you can use this code:
CODE
C=DAT1.A CD0EX D0+10 % D0 point on the Backup name
A=0.A A=DAT0.B D0+2 CD0EX % Ab: nb chr in the backup name, D0 point after
the name size
?A=0.A { A+1.A A+A.A C+A.A } % skip the name if not null
DAT1=C.A RPL % with the address of the object
embeded on the stack and return to RPL.
ENDCODE

regards, Cyrille.
