Gemini User's Manual
Turn your computer "on:' Follow the set-up requirements, if
any (such as the selection of the printer interface mode). Load
BASIC and turn "on" your Gemini. The "Power;' "Ready;' and
"Online" lamps should be lit on Gemini's control panel.
Type in the reference-program listing, Figure 5-1 making the
modifications outlined in the appendices for your computer
system_
Note:
You should "proofread" each line you type in before entering
it. If you want your program to look like Figure 5-2, your program
listing must look exactly like the one shown in Figure 5-1 (subject,
of course, to minor changes for computers other than the IBM-PC).

Before You Run the Sample Program
•
62
The program you just typed in was a long one, but it illustrates
•
about one-half of the features available on Gemini. Before we run
the program, let's utilize Gemini as a line printer_ Create a program
listing by typing LLiST. You can use this listing to double-check
•
that you have correctly entered the reference program (Figure 5-1)_
If you discover any errors, correct them. Then create another listing
•
by entering:
and then,
WIDTH
"LPT1:"~
255
LPRINT CHR$(15)
LLiST
The WIDTH command told the BASIC program that your
printer could print as many characters as it wants per line. The
CHR$(15) was sent to tell Gemini to print in "reduced" type of 17
characters per inch (CPI). By using the reduced type, full
136-character output (Figure 5-1) can be printed on the Gemini-10X
and 233 characters on the Gemini-15X.
