Load Turbo Assembler like this LOAD"tasm74fx.prg",8,1
and start it with run 

"{" is the backarrow key in document.


CURSOR MOVEMENT
---------------

CRSR LEFT/RIGHT  - move left/right one position in line
CRSR UP/DOWN     - go up/down a line
RETURN           - insert a line (if insert line mode) and go to this line
SHIFT+RETURN     - jump to next line
F1/F7            - scroll 20 lines up/down
F2/F8            - jump to source-code start/end
{CRSR UP/DOWN    - scroll 200 lines up/down
{Q               - goto to beginning of line
{N               - goto line #
{Y               - goto bottom line
DEL              - delete character left cursor
INST             - auto insert char mode on/off
{DEL             - delete actual line
{INST            - auto insert line mode on/off
{RETURN          - insert a line from cursor position

NOTE: after you leave line TURBO-ASM automatically checks its syntax.


SETTING TABULATORS
------------------
{7  - set cursor tab (e.g. where cursor jump to after RETURN)
{8  - set sourcecode tab (max.11)


LINE OPERATIONS
---------------
{2      - writes ';---------------------------------------' line
{/      - delete from cursor to end of line
{SPACE  - fill up line with SPACE
{^      - (up arrow) copy line
{=      - cut line
{~      - (pound) paste line
{Z      - undo line (imediately after {2, {/, {SPACE, {~)


BLOCK AND MARK OPERATIONS
-------------------------
{M  - set mark (#0-9), blocks start (#s) or block end (#e)
{G  - goto mark (#0-9)
{;  - kill mark (0-9)
{:  - list all marks
{B  - block operations: write (to ASCII SEQ file), kill, copy.
{E  - insert (IMPORT ASCII SEQ) file from disk to current position

NOTE: never mark first line of source-code as block start


SEARCH & REPLACE
----------------
{F   - search a string
{H   - search next occurance
{R   - replace string1 with string2, search first ocurrance
{T   - replace & search next replace
{Y   - replace all occurances

FUNCTION KEY PROGRAMMING
------------------------
{F1  - Reset funcion keys (F3=.word, F4=assemble&run, F5=.byte, F6=del line)
{A   - Input all characters (exit with "{"); to get "{" press "{" twice;
       useful when define F-keys
{K   - press F-key (F3-F6) to redefine


DISK OPERATIONS
---------------
{*  - disk directory
{@  - disk status
{D  - disk command
{P  - set EOR-code for coding source-code
{W  - writes all source-code to ASCII SEQ file (EXPORT)
{L  - load source-code
{S  - save source-code (possible overwrite with @: prefix)

NOTE: 1. TURBO-ASM  loads  its  source from top ($8FEB) to bottom
         ($0800)  of memory and crunches its opcodes, numbers by own
         (like BASIC tokens).

      2. By  saving  and  loading  source-code TURBO-ASM. also saves
         and loads configurations like colors, F-keys, marks and
         actual cursor position.

MEMORY OPERATIONS
-----------------
{6        - converts memory block between addr's to source-code data
{J        - dump memory block between addr's
{SHIFT+F  - fill memory block between addr's with code
{SHIFT+L  - load to memory addr
{SHIFT+S  - save memory block between addr's


ASSEMBLING
----------
{3  - assemble to memory
{4  - list assembled file to: ?=printer, *=screen, filename=file
{5  - assemble to object (executable) file
{U  - list labels to: ?=printer, *=screen, filename=file


MISCELLANEOUS
-------------
{C        - cold start (init TURBO-ASM. and clears source-code)
{I        - init TURBO-ASM & clear unused memory
{+        - add two hex numbers
{-        - subtract two hex numbers
{V        - display memory usage: - free blocks, + used blocks
{O        - change colors
{SHIFT+K  - keyclick on/off
{1        - exit from TURBO-ASM. (SYS 36864 or SYS 333 to restart)

NOTE: {V works incorrectly in range $E000-$FFFF, b'coz reads I/O & KERNAL
      (with Action Replay's crashes quite nicely)


EXPRESSIONS
-----------
The assembler works with 8 and 16 bit numbers with following notations:
$            - for hex numbers
%            - for binary numbers
! (or none)  - for decimal numbers
"x"          - for characters

Allowed operations in expressions (in high-to-low hierarcy order):
( )          - brackets
* /          - multiple, divide
+ -          - plus, minus
: & .        - EOR, AND, OR operations

Special operations:
<            - lower byte of 16 bit expression
>            - higher byte of 16 bit expression
*            - actual assembling addr or define object-code start (*=start)

NOTE: 1. Never use label after label=* or likewise combination.
      2. Don't use area between $E000-$FFFF (reserved for TURBO-ASM labels).

Labels:
The first 8 characters recognized and all remain truncated.

PSEUDO OPS
----------
.OFFS addr                - set object-code displacement (by adding addr)
.BYTE byte1,byte2,...     - convert bytes
.WORD word1,word2,...     - convert words
.TEXT "text1","text2",... - convert text strings
;                         - comments following


Some bugs removed by me:
1. Some versions of TURBO-ASM. (V6.0 tronic/rizing) fails with command {G.
2. {V now patched for Action Replays.
