FOR EXAMPLE:
10 IF X^1 THEN BEGIN: PRINT "X = 1 IS TRUE"
20 PRINT "SO THIS PART OF THE STATEMENT IS
PERFORMED"
30 PRINT "WHEN X EQUALS 1"
40 BEND: PRINT "END OF BEGIN/BEND STRUCTURE":GO
TO 60
50 PRINT "X DOES NOT EQUAL 1":PRINT "THE STATEMENTS
BETWEEN BEGIN/BEND ARE SKIPPED"
60 PRINT "REST OF PROGRAM"
If the conditional (IF.THEN) statement in line 10 is true, the state
ments between the keywords BEGIN and BEND are performed,
including all the statements on the same line as BEND. If the
(IF.THEN) conditional statement in line 10 is FALSE, all statements
between the BEGIN and BEND, including the ones on the same pro
gram line as BEND are skipped, and the program resumes with the
first program line immediately following the line containing BEND.
The BEGIN/BEND essentially treats lines 10 through 40 as one long
line.
The same rules are true if the ELSE:BEGIN clause is specified. If the
condition is true, all statements between ELSE:BEGIN and BEND
are performed, including all statements on the same line as BEND. If
false, the program resumes with the line immediately following the
line containing BEND.

BLOAD
—Load a binary file starting at the specified memory location
BLOAD "filename"[,Ddrive number][<ON | ,)Udevice
number][,Bbank number][,Pstart address]
where:
• filename is the name of your file
• bank number lets you select one of the 16 BASIC banks
• default bank is the bank last specified in a bank statement,
otherwise it is bank 15.
• start address is the memory location where loading
begins
• default drive is drive 0 of unit 8.
A binary file is a file, whether a program or data, that has been
SAVEd either within the machine language monitor or by the BSAVE
command. The BLOAD command loads the binary file into the loca
tion specified by the start address.
