HP 50g Unallowed Names

[MNH]

Hello,

I would like to discuss the use of unallowed names. Please refer
to http://www.hpcalc.org/hp48/docs/programm...dnames.txt. The
SYSEVAL # 05B15h works on my HP 50g. I created a variable named
'13952'. Why does ORDER return ORDER Error: Bad Argument Type
when '13952' is included in a list of variables? Would anyone
like to share their ideas about how they would use unallowed names
in their programs?

Regards,

Mark
