INKEY$ Used in the form I = INKEY$ - equivalent to Basic I = ASC(INKEY$).CHR$ As Basic, but only accepted in PRINT statements.

The following Basic functions are also supported: WINDOW As Basic, including WINDOW SWAP.WHILE/WEND As Basic, but loop must not be jumped out of.To simulate RUN 100, use CLEAR : GOTO 100. RUN As Basic, but no line number allowed.REM As Basic - the remainder of the line is entirely ignored by the compiler.If the argument is preceded by #n, (where n is a number between 0 and 8), output will be directed to the appropriate screen window (or to the printer if #8 is used). A semi-colon may be appended as in Basic, but not a comma. PRINT As Basic, except only one argument allowed (number, variable or quoted string) per PRINT statement.ORIGIN As Basic - that is, both ORIGIN x,y and ORIGIN x,y,l,r,t,b are supported.THEN (line number) must be written as IF. THEN As Basic but no ELSE statement allowed, and statements such as IF. GOTO/GOSUB As Basic, except that the ON.NEXT As Basic, except that the loop must not be jumped out of, and each NEXT (which must not be followed by a variable) will always refer to the most recent FOR. CLEAR No parameters allowed - simply clears all variables to zero.CALL No parameters allowed - only the address to call.The accepted commands, together with any limitations, are shown below: When your program has been successfully compiled, you may save it to tape or disk as a binary file (using the addresses generated at the end of the compilation) or run it immediately by CALLing the start address. If any errors are reported, you should correct the offending line and re-compile from the beginning. Now merge in the compiler itself (if you don't still have it in memory) and run it using RUN 1000 this may take a few minutes if your program is very long, but the compiler will keep you informed of its progress at each stage. You must now renumber it so that the last line number is less than 1000, and ensure that the last line of the program terminates with an END statement. When you are satisfied with the program's performance, you should then save it in case you wish to modify it at a later date. (If saving to disk on the CPC464, be sure to save it as an ASCII file - otherwise you will not be able to merge it later.) Next, load or type in the program you wish to compile, and test it thoroughly under Basic. To use the compiler, type in the listing exactly as shown (except that all REM statements may be omitted if desired) and save it to tape or disk. Over 50 Basic keywords are supported by the compiler (including those dealing with sound and graphics), but there are some restrictions on the use of variables and expressions. This invariably results in faster and more compact programs. This Basic compiler enables programs written in Amstrad Basic to be compiled directly into machine code. ★ Dieser Text wird in seiner Originalfassung präsentiert ★ ★ Este texto se presenta en su versión original ★ ★ This text is presented to you in its original version ★ ★ Ce texte vous est présenté dans sa version originale ★
