Thanks Mark, much clearer now. Perhaps mentioning this distinction in the doc may be worthwhile to save someone else from falling into this rabbit hole? Thanks again.

Hi Mark, Thanks for your response. Sorry, I don't understand your distinction between "interpreted as' and 'is' ? If Regina interprets the string as a Hexadecimal string then why doesn't it process it as such?

Thanks Mark - but I'm confused ??? On p.18 there is a definition of Hexadecimal string Hexadecimal String Any hexadecimal (0-9, a-f, A-F) characters, grouped in pairs, enclosed in single or double quotes and immediately followed by 'x' or 'X' is interpreted as a hexadecimal string. (The "X" is outside of the quotes). If the first group has an odd number of characters, a zero is prepended. Examples: Hexadecimal String '0def'x "01 02 03"X '123 45'x → same as '01 23 45'x on page 126 X2D(hexstring [,length])...

Further both error messages use the term " X2D argument 1 must be a hexadecimal string; " perhaps the doc needs to be clearer and unambiguous ?

Hexadecimal seems to have a Hex ?

Silly syntax typo causes Regina to CRASH

No - I thought I was comparing two character strings - both enclosed in quotes. I didn't realise they would be converted to numeric values - and certainly not numeric values in scientific notation. I learnt a few lessons from this one. - Sorry for the false alarm.
