C1 Assembler

Computer One Assembler is a fast single pass 68000 machine code assembler written in machine code for speed an compactness.

The assembler supports only a limited number of directives:

• DC - Define Constant
• DS - Define Storage
• DBC - Define Constant Block
• EQU - Equate
• ALIGN - Align to word boundary
• XREF - External Reference
• XDEF - External Definition
• IF…{ELSE]…ENDIF - Conditional Assembly.

Originally, the most notable exceptions were GET and INCLUDE commands to automatically add external files to the main file - although this can be overcome using the merge file facility in the editor. A linker was not originally included with the package, but had been added by May 1985, along with the INCLUDE command.

Advertised features included:

• 68008 Assembler
• Full syntax checking
• Full-screen editor
• Comprehensive user manual
• Integrates to Pascal and SuperBASIC.
