Instruction Set

• psh \ : Pushes an integer onto the stack
• add \ \ : Adds the content of registerb to registera
• sub \ \ : Substracts the content of registerb to registera
• mul \ \ : Multiplies the content of registerb to registera
• div \ \ : Divides the content of registera by registerb
• pop : Pops the stack
• mov \ \ : Copies content of registerb in registera
• dst : Prints the stack
• drg \ : Prints the content of the specified register
• hlt : Stops the program
• tee \ \ : Test if registera == registerb
• tne \ \ : Test if registera != registerb
• tll \ \ : Test if registera < registerb
• tmm \ \ : Test if registera > registerb
• tel \ \ : Test if registera <= registerb
• tem \ \ : Test if registera >= registerb
• jmp \ : Jump to \ if Eq register is true
• prt \ : Prints the character corresponding to register value
• dmp : Dumps the stack and the registers
