Additional new graphics modes on the Apple IIgs are likewise not supported. Applesoft, however, does not provide support for this mode, and must rely on supplemental machine-language routines in order to utilize it. This mode essentially duplicates the resolution of the original hires mode, but including all 16 colors of the lores palette. Beginning with the Apple IIe, a new 'double-high resolution' mode, based on a mode introduced on the Apple III computer, became available on machines with 128k of memory. Error-trapping, allowing BASIC programs to handle unexpected errors by means of a subroutine written in BASICĪpplesoft supports the Apple II lores graphics display, where 40 color 'blocks' horizontally, and up to 48 blocks vertically, can be displayed in 16 colors, with commands to plot individual blocks and horizontal or vertical lines as well as the hires mode, where six colors (a fixed subset of the lores palette of 16 colors) can be displayed in a resolution of 280 horizontally by 192 vertically (with some limitations on horizontal placement), with a command to draw points or any diagonal lines onscreen.User-defined functions: simple one-line functions written in BASIC, with a single parameter.CHR$, STR$, and VAL functions for converting between string and numeric types (both languages did have the ASC function).DATA statements, with READ and RESTORE commands, for representing numerical and string values in quantity.Single-precision floating point variables with an 8-bit exponent and a 31-bit significand and improved math capabilities, including trigonometry and logarithmic functions.Multidimensional arrays (numbers or strings).This allows for string arrays DIM A$ ( 10 ) resulted in a vector of eleven string variables numbered 0–10. Atomic strings: A string is no longer an array of characters (as in Integer BASIC and C) it is instead a garbage-collected object (as in Scheme and Java).While Applesoft BASIC is slower than Integer BASIC, it has many features that the older BASIC lacks: Applesoft was designed to be backwards-compatible with Integer BASIC and uses the core of Microsoft's 6502 BASIC implementation, which includes using the GET command for detecting key presses and not requiring any spaces on program lines. Chipmunk basic mac os 8.6 code#The Applesoft license also saved Microsoft from near-bankruptcy when they licensed BASIC to Commodore for the PET in an agreement that proved unexpectedly costly for them.Īpple reportedly obtained an eight-year license for Applesoft BASIC from Microsoft for a flat fee of $31,000, renewing it in 1985 through an arrangement that gave Microsoft the rights and source code for Apple's Macintosh version of BASIC. Making things more problematic was that the rival Commodore PET personal computer had a floating point-capable BASIC interpreter from the beginning. As Wozniak-the only person who understood Integer BASIC well enough to add floating point features-was busy with the Disk II drive and controller and with Apple DOS, Apple turned to Microsoft. Steve Wozniak had never added floating point capabilities to Integer BASIC as he did not consider them necessary for gaming and educational software, the two primary tasks he envisioned for the Apple II. Integer BASIC is limited to whole numbers between −3277 and caused problems for users attempting to write business applications with it. One of the most common customer complaints about the computer was BASIC's lack of floating-point capability. The Apple II was unveiled to the public at the West Coast Computer Faire in April 1977 and became available for sale in June. ![]()
