In Commodore mode, chr$(147) works the same as the escape code
chr$(27)"N"chr$(6) and chr$(19) turns off paging as does the se-
quence
chr$(27)"O". chr$(147) can be very useful in long BASIC
programs. With this code, you can print out a long listing skipping
over the page perforation. An example of this application for
LISTing
long BASIC programs:
open4, 4, 7:cmd4, chr$(14 7) ;:list:print#4:close4

The ESC 1 (lower case "1") command sets the left margin at column
n. Printing starts at column (n + 1). To use it, send ESC I followed
by the ASCII code for the column number you want. For example,
chr$(27) "1" chr$(10) sets the left
margin at column 10, leaving 10
blank columns (printing will start in column 11). The actual width
of the margin is determined by the character width in effect when
the
margin is set. Later changes in the character width do not affect
the
width of the margin.
If the margin setting exceeds the maximum number of columns in a
line for the character width in effect, the setting is ignored.
