If value of parameter 0567 N STEP is other than 0, the block number is increased by the value
given at the parameter for each push of the <ENTER> key and this is automatically
inserted to the beginning of the new block at address N.
If for example the value of parameter is 10 the block numbers are increased by ten: N10, N20,
N30, ...
Moving the cursor
As the effect of right key the cursor goes to the next character. Should the line (last
character or space) on the screen end earlier than the right verge of screen, the cursor goes to
the first character of the following line, if there is. If the text ends there the cursor stands still.
As the effect of left key the cursor goes to the previous character. Should it be on the
left verge of the screen, the cursor goes to the finishing character of the previous line,
independent of where the previous line ends. If the text starts there the cursor stands still.
As the effect of down key the cursor goes to the following line. Should there neither be
character nor space in that column of the next line it goes to the last character of the line. If
there is no text in the succeeding line what so ever the cursor stands still.
As the effect of up key the cursor goes to the previous line. Should there neither be
character nor space in that column of the last line it goes to the last value character of the line.
If there is no text in the previous line what so ever the cursor stands still.
As the effect of the page down key the cursor goes to the following page, so that a
whole block is seen on the bottom of screen and it appears after the last character of the block.
.
As the effect of the page up key the cursor goes to the previous page so that the first
line of the screen always shows the beginning of a block (code s) and it appears on the first
character. In case no more paging can be done, it goes to the first character of the text.
Delete
When pressing key <DEL> the character on which the cursor stands is deleted, while
the characters behind step forward. If due to this, the word in the next line has now enough
room in this line, it also steps forward.
In case a space separating two words is deleted, the word drawn together is written in one.
Should the space be at the end of a line, i.e., the two words be in other lines (and the block not
finished yet, i.e., the following character not being s) the word is written in one and occurs
together with the cursor in the succeeding line.
If characters are deleted from a word at the beginning of the line and the shortened word can
already be displayed in the previous line the word together with the cursor occurs there. If
when pressing delete key the cursor stands after the last character of a logic line (block)
linefeed character s is deleted and the two blocks are drawn together.
