Handbook#


The BiboAssembler is a fast and compact Assembler for the Atari 8-Bit. The Assembler is available as File- and as Module-Version (Cartridge). The File-Version includes also a small Machine-Language Monitor.

This Assembler was written by Erwin Reuß and Peter Bee of CompyShop in 1986. Many CompyShop Products (Speedy 1050, BiboMon, CompyShop Grafic Demos etc) are written with this tool.

The ATARI Bit Byter User Club is holding all copyright to this fine tool. There is a plan on re-sourcing the Assembler (task in progress by Martin Metz) and publishing the Assembler Source under the GNU Public License as Open Source Software.

We have also the plan to publish an english translated version of the Bibo Assembler Handbook. But this will take time. For now we have a short description of the available commands.

Short Description#

Loding and starting#

BiboAssembler can be load as a binary file from any DOS System. Make sure that BASIC is off and all Cartridges are removed. BiboAssembler works well with Ramdisk Drivers and Harddisk.

The Editor#

The BiboAssembler Editor is a line Editor with Line-Number, similar to Atari Basic. It can be used like the Atari Basic Editor. Inverse Characters cannot be used except when eclosed in double-quotes. The ASCII Character with Value Zero (the heart in the ATASCI Font) cannot be used. If you need to specify this Char you have to write

 .HX 00 ; Equals ASCII Value Zero 

Auto Numbering#

BiboAssembler supports automatic Line Numbering. Pressing the TAB-Key in the beginning of a new line will insert the next line number. The steps for line numbering can be changed with the command

INC steps, first linenumber

Example:

INC 10, 1000

The command "NUM" will switch on automatic line numbering.

NUM steps, first linenumber

Example:

NUM 10, 1000

Automatic Line Numbering can be switch off with the BREAK-Key.

deleting Lines#

Lines in the Editor can be deleted with the command "DEL"

Syntax: DEL first line, last line

Example: DEL 1000,1100

will delete lines 1000 to 1100 (without asking).

erasing the Editor Buffers#

The command "NEW" will reset the full editor and will rease all sourcecode in the Editor Buffers.

Line Format#

A B C D E
00010  LABEL   LDA $4567  Comment

  • A Line Number- 0 to 64000.
  • B Label - 1 to 128 Characters First Char must be a Letter (exceptions are local label). The Label must follow direct or with one blank after the line number
  • C Opcode - three chars, either normal 65(C)02 Opcode or Pseudo-Opcode. Must be sepertaed from Linenumber by two blanks or one blank from Label.
  • D Parameter - Address, Value or Filename. Must be direct or with one blank after the Opcode
  • E Comment - Must be two blanks away from Opcode or one blank from Parameter

A line can be 128 Chars max. Comments can start anywhere with "*" or ";". One hyphen "-" will be expanded to a delimiter line.

Example

1000 -

will get

1000 ---------------------------

List#

The Command List will list the source code

Syntax: LIS first line, last line

Example: LIS 1000,2000

Abbrev: L.

Listing can be stopped with CNTRL+1 and can be stopped with the BREAK-Key. Also valid:

LIS 1000,
will list from line 1000 to the End.
LIS START
will list from Label "START" down.

Searching and Replacing#

The Command "FIN" will search Strings in the Source Code.

Syntax: FIN string

Example: FIN LDA will list all occurrences of LDA in the sourcecode.

The Command "REP" can be used to replace STrings in the code.

Syntax: REP "string1"string2"

Example: REP "LDA"LDX" will replace all occurances of "LDA" with "LDX" in the Sourcecode.

Copy and Moving Sourcelines#

(TBD)
