If you installed everything in the proper way, you will be able to call the compiler:

  ugbc.xxxx

where xxxx is one of the targets:

• Atari 400/800 (atari)
• Atari 1200XL (atarixl)
• Atari 600XL/800XL (atarixl)
• Atari XE Video Game System (atarixl)
• Commodore 128 (c128)
• Commodore 64 (c64)
• Commodore PLUS/4 (plus4)
• Commodore VIC-20 (vic20)
• Dragon 32 (d32)
• Dragon 64 (d64)
• Dragon 200-E (d64)
• Olivetti PC128 Prodest (pc128op)
• Thomson (mo5)
• Amstrad CPC (cpc)
• ColecoVision (coleco)
• MSX (msx1)
• SEGA SC-3000 (sc3000)
• SEGA SG-1000 (sg1000)
• ZX Spectrum 48K (zx)

The output contains the valid options.

In order to compile a BASIC source you can use this command:

 ugbc.xxxx source.bas -o source.yyy

where yyy is the expected file format.

For example, in order to create an executable program for Commodore 64:

 ugbc.c64 source.bas -o source.prg
