Your LISTing will not show those spaces. Only reset can interrupt a WAIT. In addition to the true metasymbols, the special symbol: It Is applespft usually desirable to use this command if the cursor is below the bottom margin of the text window: As the cursor moves, each character it crosses on the screen is copied into APPLE II’s memoryjust as if you had typed the character.

Equivalent positive and negative values may be used interchangeably. VTAB will move the cursor up or down but not left or right.

Applesoft BASIC Quick Reference

If FOR loops are nested more than 10 levels deep, the ‘. In graphics mode, VTAB will move the cursor into the graphics area of the screen. Serious programmers often keep two versions of their programs: Array names are not stored with their values, so an array may be read back using a different name than that used with the STORE command. SAVE Stores a program on cassette tape.

When more than one line is to be listed. String array variables use 3 bytes for each array element: Functions which are defined on a given arithmetic type will convert arguments of another type to the type for which they basid defined. To escape, use reset Ctrl C return.

However, the comma and the colon and Ctrl X and ctrl M are not accepted as characters in the literal. If all three parameters are specified, then WAIT performs as follows: The screen is Ignored by this command, and nothing is changed on the screen.

I’OK GI Returns the current horizontal position of the cursor- This is a number from at the left margin to 39 at the right margin.


When a new function is defined by a DEF statement, 6 bytes in memory are used to store the pointer to the definition. Each can be converted to the other by functions provided for the purpose.

Upon return, the floating-point value will be in the floating-point accumulator. If two game controls are read in consecutive PDL instructions, the reading from the second game control may be affected by the reading from the first. This allows protection of variables from high-resolution graphics in computers with large amounts of memory.

Amazon Second Chance Pass it on, trade it in, give it a second life. The prompt and cursor are moved to the last line of the screen. In immediate-execution mode, an instruction must be typed without a line number. In the example, 1. In this case, its use will cause the prompt character ] to appear in column J of the next lower line, followed by the cursor. If the final results are eight zeros, the test is repeated.
