If “non-printable” codes aregiven, ie those codes fmm OOhthrough IFh and
71%,these codes will be enclosed in angle brackets, for example cDC1>.
The name in the angle bracketsis that assigned to the code in the ASCII con-
vention. The name of the character should not be used, the binary value
should”beinput. In the same way, it should be noted that the angle brackets
are not to be input - they are merely there as delimitem in the printed text.
Of course, in a program, a meaningful variable name can be given to these
charactem, for instance (the following example is written in BASIC):
10
ESC$=CHR$(27) :BS$=CHR$(8)
20 LPRINT ESC$;BS$;

Mostof the
following command codes are available in both the standard
mode and the IBM emulation mode. If a command is common to both
modes, the descriptive heading is followed by “Both”. If the command is
specific to one mode, then either “Standard” or “IBM” will follow the
descriptive heading. Occasionally, there am two identical commands to
perform the same function. In these cases, the relevant sign follows the
escape sequence.

In the following descriptions, first the function of the command sequence is
given. This is followed by the emulation for which this command is
appropriate (“Standard”, “Both” or “IBM”).
