no operand is entered, the pointer line is deleted. When the pointer line is deleted, the pointer is
moved to the top line of the buffer. The following example shows a C command to change lines
5 through 7, replacing them with four lines:
1C5-7
LOD MOV
AI
CI
JLT
1,4
4,1
4,WA+60
SUM
The following example shows a C command to change the pointer line and the two lines that
follow the pointer, replacing them with two lines:
1C3
LOD MOV 1,4
CI 4,WA+60
4.5.4.2 Insert (I). The Insert command permits input of one or more lines following the pointer
or a specified line. The syntax for the I command is as follows:
I[<k>]
Enter as many lines as required. Follow each line with a carriage return; follow the last line with
two carriage returns. When k is in the range of 1 to 9999, insert lines following line k. When k is
0, insert lines ahead of the top line in the buffer. When k
is
omitted, insert lines following the
pointer line. The following example shows the use of the I command to insert two lines
following line 10:
1110
CKON
DEC 7
4.5.4.3 Move (M). The Move command moves a specified block of lines to a specified location
and deletes the lines at the previous location. The block is specified by first and last line
numbers, or by a number of lines preceding or following the pointer. The location is specified as
a line number, or as the pointer. The syntax for the M command
is
as follows:
',-
Line s through line t are moved, or n lines with respect to the pointer are moved. When n is
preceded by a minus, sign, n lines preceding the pointer line, but not the pointer line. are moved.
When n is unsigned or preceded by a plus sign, n lines beginning with the pointer line are moved.
The specified lines are placed following line r when r is greater than zero. When r is zero,the
specified lines are placed ahead of the top line in the buffer. When r is omitted, the lines are
placed following the pointer line. Numbered lines moved by the Move command retain their
, original line numbers, if any. When the pointer line is moved, the pointer moves with it. When s
r
and t are specified, r must be less than s or greater than t. When n is specified, r may not be
omitted. The following example shows an M command to move lines 6 through 8 to follow line
