The UI commands may be used to enter an object name and details in the following way (minimum abbreviations are used):
Source names may be defined with any letters inside brackets used as optional descriptors, e.g. AL(VIN) may be recalled as ALVI, ALV or AL.
An alternative way of entering commands is to put all of them on a single line leaving spaces between each trailing field and the next command word. NGC3456 may be input, using minimum abbreviations, as follows:
SO NGC3456 R 10 11 12.3 D -03 07 14 EQ B1950
The semicolon may be used as an alternative to Return as a command terminator. For example, each of the commands RA and DEC expect one sexagesimal argument with 3 fields (hrs mins secs or degs mins secs), but right ascension , declination +30 and equinox 1950 is abbreviable to:
R 1; D 30; E B1950
The command processor ceases looking for further arguments for R and D on detecting the semicolon and begins processing afresh at the next character.
