Editor commands which use filenames
can be used with or without the
quotes eg. S "name" will be read the
same as S name. However pseudoopcodes
in the source file which use
filenames must be given with the open
quote, but you may skip the closing
quote.
More than one error may be found
on a line, but may be related eg. BNE
ALAB - will give "BRANCH TOO
FAR" and also "LABEL UNDE-
FINED" if ALAB is not present, as
it is trying to branch to an unknown
destination.
Getting it all in
Four Basic loaders are used to POKE
in the main assembler code. These are
named BLOCK I - BLOCK 4. RUN
each of these programs in order, and
when the message BLOCK 4 OK is
displayed enter as direct commands:
POKE 43,0: POKE 44,110: POKE
45,0: POKE 46,160: SAVE "MACRO
ASSEMBLER",8 (Cassette users read
,8 as ,1).
Now reset, and load the assembler

When READY, appears type
NEW followed by SYS 28160 to
initialise the assembler with a cold
start.
The configure program can be
typed in and saved as usual with SAVE
"CONFIG",8. This must have the
main assembler code present before
RUNning.

10! This is "SOURCE3"
20 BASICAD=43 ! give the label for
the above files
30 R ELINK "MAIN"! loop back to
the main file
When linking from cassette, you
will be told to insert a file and press
a key, this is due to the need of
rewinding etc. Linking from disk is
automatic.
As stated the TOP LEVEL
SOURCE file is the only file in which
a DINCLUDE directive can be used.
Its function is best used to set up a
type of batch file, a small file which
'calls' the main bulk of the source, a
typical batch file could be:
10 ! TOP LEVEL SOURCE FILE
20 OUT 3 ! sends output to screen
30 SYM "KERNALSYM" ! reads
symbols for the KERNAL routines
40 LOPEN. MAC ! define a macro
called "OPEINLMAC"
50 DINCLUDE "MAIN I " ! includes
the main code part 1
60 DINCLUDE -
MAIN2" the main code part 2
