The alphanumeric entry screen is used to enter strings consisting of letters,
numbers, and other characters. The cursor may be positioned within the
entry line using the
and
keys. If a character is entered over an
existing character, that character will be overwritten. Use the
and
keys to switch between the entry line and the keyboard as well as to
move within the keyboard. To select a character to add to the string, use
the cursor keys to position the cursor over the desired character, and then
press the
key to add that character to the entry line.
On the right side of the keyboard are special functions. BKSP is used to
move the cursor in the entry line one place to the left, deleting the
character that was to the left of the cursor and moving any character at or
to the right of the cursor one place to the left. PAGE is used to change the
keyboard character page. For the English language, this switches between
upper and lower-case alphabetic characters. SAVE stores the string from the
entry line into the parameter. Alternately, if the active cursor is moved to
the entry line,
may be pressed to store the string from the entry line
into the parameter.
