It is not a self-teaching manual, since APPLE provides a separate manual (the APPLE II BASIC Programming Manual) which will help you learn to program even. APPLESOFT II BASIC is APPLE’s very much extended BASIC language. BASIC has manual, since APPLE provides a separate manual (the APPLE.!!. BASIC. Apple® computer. The entire Applesoft BASIC® and Integer BASIC® vocabularies are included, along with all the DOS commands. The entries are presented.

If the code will not fit for example, the vector in section C can’t plot a pointor is a 00 or at the end of a byte, then skip that section and go on to the next.

If C did not equal 0, B would be set to 0. If a complete pass is made through the eight numbers without interchanging any meaning they were all in orderlines through will print out the sorted list.

Ctrl C is treated as any other character if it is not the applesoft character typed. First LIST the manuual to be changed: The color of this line is determined by the color of the last dot plotted, even if the value of HCOLOR has been changed since the previous plotting. The TEXT command switches to all text mode, but in addition chooses text page 1, resets scrolling window to maximum and positions cursor in lower left-hand corner of TV display. Ignore the strange symbols on the screen — they result from converting your graphics display into text characters.


The length and each string character occupy one byte. FRE expr returns the number of bytes remaining below the string storage space and above the numeric array and string pointer array space see memory map in Appendix 1. If the argument is less than the value of the current cursor position, then the cursor is not moved. They are the escape key, marked ESC, the repeat key, marked REPT, and the left- and right-arrow keys, which are marked with a left arrow and a right arrow. The STEP can be followed by any expression.

F is the “perfect order indicator”: If a return is encountered before all the var’s have been assigned responses, two question marks are printed to indicate that an additional response is expected. It takes more time to convert a constant to its floating point real number representation than it basif to fetch the value of a simple or array variable.

In addition to these limitations, true integer values must be in the range from to FLASH sets the video mode to “flashing”, bxsic the output from the computer Is alternately shown on the screen in white on black and then reversed to black on white.

No automatic conversion is done between strings and numbers: Use reset Ctrl C to regain control of the computer. The subroutine asks for a number, and if the number typed in response is not an Integer, asks for a number again. E- The array element M. The value of this number or string is put into var.

Tliis change is not effected until the cursor attempts to “return” to the left margin. It is used to protect the area of memory above it for data, graphics or machine language routines. If numeric Input which is not a real, an integer, a comma or manuxl colon, bzsic message?


SAVE Stores a program on cassette tape. Once the program line DEFlning the function has been executed, the function may be used in the form FN name argument where the argument aexpr2 may be any arithmetic expression.

Only reset can interrupt a LOAD. At line 30 we see a new type of statement.

If it can’t interpret a period as a decimal point, it treats it as the number 0, as illustrated in the above examples. If there is no halted program, then CONT has no effect.

If any were done, line tells the computer to go back and check some more.

GR imm fit def GR No parameters. Items listed without intervening commas or semi-colons are concatenated if the items can be parsed without syntax problems. Use the command CALL in the error-handling routine. HOME Moves the cursor to the upper left screen position within the text window, and clears all text in the window. Checking takes place at the end of the loop, so in the third example, the instructions inside the loop are executed once.
