![]() As on the original HP-42S, BST will start auto-repeating after a while and SST will NULL after a couple of seconds if you press and hold ▲ or ▼ respectively. Press and hold the SHIFT key while pressing ▲ or ▼ in order to execute BST or SST respectively when in alpha input mode. Un-shifted R/S still behaves as usual allowing program execution to resume after inputting alpha data to a program.įunction arguments (eg. Local labels LBL A and LBL a and global labels LBL "ABC", LBL "123" and LBL "A123" work as expected. So if you do 2 ENTER + you will have 4 as answer. iv)The content just entered goes to line y and line x. ![]() iii)The content of line x goes to line z. ii) The content of line y goes to line t. i) The content of lines t and z are lost. Two-digit local labels LBL 01 are not available. When you enter a number (say 2 ENTER) what happens is the following. Switch to standard HP-42S mode to get them. This means that for compatibility purposes the display should be a multiple of the original 131 pixels width. Shifted R/S gives '?' instead of entering/leaving Prgm mode.ĪSTO, ARCL, '%', 'pi' and 'E' (exponent) are not available. As mentioned in the Free 42 documentation it is not always possible to use a floating-value display scale ( source ): Non-integer display scales are supported in Free42 for Android, iOS, and MacOS, release 2.0.24g and later. Shifted ÷, ×, - and + give '÷', '×', '-' and '+' instead of the alpha characters. SHIFT 0 (zero) to SHIFT 9 give the digits 0-9 instead of the alpha characters. SHIFT A to SHIFT O give the same characters. The function keys still allow input in HP-42S mode.Īll alpha keys A-Z give the expected characters.
