If you find yourself defining characters in small groups, the same tech-
nique can be used to store part of the CHR$(27) "&" command:
Z$=CHR$(27)+"&"+CHR$(0)
Z$ can be used to define each new string of characters with a simple
command such as either of these:
LPRINT Z$"AZ";
LPRINT Z$CHR$(l28)CHR$(159);

STRATA

Your current program uses eight user-defined characters,
which will be used again in a later chapter. For now, delete
lines 80, 90 and 165 and change line 180:
180 LPRINT " 147646 12345678"

Save the current program as STRATA.
