Returns the common logarithm of n to the base 10 Control flow block that evaluates the boolean expression and returns Branches forward or backwards depending on It reads whole lines and doesn't end until n characters are received Function is similar to LINE INPUT or INPUT$ in both respects filepos = 1 (the beginning of the file) Reads from file to a buffer or variable

Returns the next free file pointer that can be used. Control flow block that repeats a number of statements Returns the whole number (truncating any fractions). Exponential Function, returning the value of e raised to the power n Function returns the value of the environment variable Must be used to end a multiple line IF. Returns a non-zero value if the file is at the end. Control block that loops until expression returns true
if string, you have an option of defining its length size any legal variable name (max 80 characters) Used to store numeric and string constands used by the READ statement. Function that returns the cosine of n (in radians) If arguments are omitted, then all open files are closed Converts expression to a single precision number Converts expression to a double precision number Conversion function that returns the rounded integer expression Function returns the character of ASCII value n Function returns the ASCII value of the character Function returns the absolute value of integer expression n No expressions like 32 * 1024, just an integer value is accepted Do not use 32K, instead write 32767 or 1024 for 1K strings The default is 255, the maximum is 32767 Defines the default length of string used You can explicitly tell the compiler to use certain libraries.ĪNSI.LIB, DOS.LIB, GRAPHICS.LIB, MM.LIB, UNIX.LIB SWAP A!, A% should return type mismatch, but doesn'tīASEC Library (extension of ANSI library) PRINT 100/0 should return a divide error, but doesn't PRINT 123456% would normally receive an illegal number in QBĭIM A$(1000) AS STRING would also receive an error ?:INPUT$(1) gives an "improper placement of quotation mark" error.

Some error correction is done without the user knowing.įor example, Error: Overflow will never occur, but the result will, I plan on wiping error messages completely with the '-whocares' switch.

So what this Linux based compiler is able to do is create DOS executables from BASIC source. Update: The hello program that compiled with the Ubuntu 64 version when renamed to HELLO64.EXE and run under dosemu worked fine. I think I'm close and willing to look a little closer if there might be interest in this. I was able to get it to compile after renaming all operator variable names to _operator. For fun I thought I would try to compile the BEC (BASIC Emulation Compiler by William Yu) on my Ubuntu 64 laptop.
