Simple compiler written in Scala that compiles dialect of BASIC to C.

Language supports:

• Numerical variables
• Basic arithmetic
• If statements
• While loops
• Print text and numbers
• Input numbers
• Labels and goto
• Comments

Example code:

# Compute average of given values.

LET a = 0
WHILE a < 1 REPEAT
PRINT "Enter number of scores: "
INPUT a
ENDWHILE

LET b = 0
LET s = 0
PRINT "Enter one value at a time: "
WHILE b < a REPEAT
INPUT c
LET s = s + c
LET b = b + 1
ENDWHILE

PRINT "Average: "
PRINT s / a
