Hola, Fernando:
Puedes conseguir esa información en este enlace, dentro del
propio MoHP:
Programación de la HP-41C
Lo que tu necesitas en particular depende de los dos flags
28 y 29, tal y como se cuenta en esa página:
Number Display Control Flags (28 to 29)
Flag 28 controls the radix and separator marks. It may be
set for American or European styles. When flag 29 is set
groups of three digits are separated with commas or points
depending on the setting of flag 28.
Saludos de V.
(In English, please ...)
Hi, Fernando:
The info you seek may be gathered from this very MoHP site,
at the link:
HP-41C Programming
What you want to accomplish, in particular, depends on these
two flags 28 and 29, as told in said page:
Number Display Control Flags (28 to 29)
Flag 28 controls the radix and separator marks. It may be
set for American or European styles. When flag 29 is set
groups of three digits are separated with commas or points
depending on the setting of flag 28.
Best regards from V.
