Questions regarding HP Roman character set

[Chris Dreher]

Thanks. I think I may have cross-wired some parts of the RPL character set with the HP Roman character set but kept it separate with other parts.

Regarding the Wikipedia sentence that contains "... because this is the codepoint the former non-breaking space (in the HP 48 series) will be transformed to", I now see what you are saying there. However, I misread it the first several times I read it. I recommend rewording it since the first sentence is very long with multiple facts. While this isn't the best, here's one suggestion:

Quote:There is no official codepoint definition for the euro sign in this modified character set. The HP 49/50 series of calculators use a different character set based on ECMA-94 / ISO 8859-1 which includes the euro symbol. When printing to the HP 82240A printers via OLDPRT/PRTPAR, the euro sign may be translated to codepoint 128 (0x80). This is because the HP 48 series OLDPRT/PRTPAR transforms the former non-breaking space codepoint to codepoint 128 (0x80). Mapping the euro sign to code point 186 (0xBA) as in HP Roman-9 would be another choice.

That said, I'm not certain that the HP 48 translates the RPL NBSP (0xA0) to HP Roman NBSP (0x80). It appears that it is translated to a regular ASCII space (0x20). I might be reading the vector wrong. Anyways, here is the vector from the PRTPAR variable since HP's code trumps any documentation they may have written for the 48-series. I extracted this from the SX and GX and confirmed the vector is the same on both calculators.

Code:
