(50g) USER key ": division" a) decimal into (pi) fractions b) no limits

[John Keith]

David is talking about an unusual use of the :: (tag) called the "null tag". For example:

6 5 > :: DROP IFT

i.e. DROP goes after the tag, not inside it. To enter that on the HP 50, type [right-shift] . [right arrow] DROP.

Note that the "null tag" is not documented, it was discovered in the olden days by someone on comp.sys.hp48.
