4.5.2.2 No Line Numbers (SN). The No Line Numbers command causes PX9EDT to omit
printing of line numbers except in the message resulting from the L command. The syntax for
the SN command is as follows:
SN
The SN command may be entered initially or at any time during the edit operation. Omitting
the line numbers when editing object code may be desirable to permit printing the entire record.
4.5.2.3 Print Margin (SP). The Print Margin command specifies the right margin for printing,
except for the message resulting from the L command. The syntax for the SP command is as
follows:
SP<S>
The right margin for printing is column s. The default value for the right margin is column 72.
The margin input must be a va1ue between 10 and 80, inclusive. If line numbers are being
printed, the line numbers are included in the margin column. The line numbers use six columns,
so
that if the right margin is comumn 72, only 66 characters plus 6 line numbers and blanks for
spacing are printed. The following example shows an SP command that specifies column 60 as
the right margin for priIiting:
?SP60
4.5.2.4 Find'Margin (SM). The Find Margin (SM) command specifies left and right limits for the
Find command. The syntax for the SM command is as follows:
SM<S>,<t>
The Find command scans from colunin s to column
t.
The SMcommand may be entered to
limit the Find command to a desired field. The default value for the scan limits is froin column
I to column 72. The following example shows an SM command that limits the scan of
subsequent Find commands to columns 8 through 25:
?SM8,25
4.5;3 POINTER COMMANDS. The pointer commands may be used to move the pointer to any
line in the buffer of PX9EDT. Initially, the pointer is at line 1. Moving the pointer with' the
Down command to any empty line causes PX9EDT to read source lines or object records from
the input file to fill the empty lines, including the line specified in the Down command. Other
commands move the
poi~ter
up a specified number of lines, or to the top of the buffer, or down
to the bottom of the buffer. The pointer commands permit the user to move the pointer as
desired for effective use of commands that identify lines by specifying a displacement from the
pointer. The pointer commands are described in the following paragraphs.
4.5.3.1 Down (D). The Down command causes PX9EDT to move the pointer down a specified
number of lines. When the specified move is to a line ,number greater than the contents of the
buffer, PX9EDT adds lines to the buffer and reads records from the inpu(file to fill these lines.
The syntax for the D command is as follows: '
D[<n>J
