For example, the following line of text would cause the speech synthesizer to identify the computer: [18] CALL SAY("HELLO I AM A #TEXAS INSTRUMENTS# T I NINETY NINE FOUR A HOME COMPUTER") Multi-word phrases are delimited with the # symbol, as #TEXAS INSTRUMENTS# in this example. Using a word not included in the speech synthesizer's built-in ...
The language retained some compatibility with its predecessors, such as the Dim keyword for declarations, "Gosub"/Return statements and optional line numbers which could be used to locate errors. An important driver for the development of Visual Basic was as the new macro language for Microsoft Excel, a spreadsheet program. To the surprise of ...
Implicit variables, suffixes, GOSUB / RETURN, numeric labels and other features are allowed in this dialect. The QB dialect (-lang qb) attempts to replicate QuickBASIC behavior and is able to compile many QuickBASIC programs without modification.
For example, a CP/M programmer might use a POKE function to allow BASIC to switch the console device to the serial port, if the system BIOS supported this. For machines with real-time clocks, a set of PEEK instructions might have been used to access the time.
Additionally, it lacks GOSUB and RETURN but does include a RND function (without arguments, returning a value between 0 and 255). [57] The language uses an array to store program lines, requiring 20,000 bytes to do so. [58] In 2023, Gordon Henderson published a Tiny Basic implementation in 6502 assembler. It is influenced by NIBL and can run in ...
"GOTO" key on the 1982 ZX Spectrum home computer, implemented with native BASIC (one-key command entry).. Goto is a statement found in many computer programming languages.It performs a one-way transfer of control to another line of code; in contrast a function call normally returns control.
PowerBASIC, formerly Turbo Basic, is the brand of several commercial compilers by PowerBASIC Inc. that compile a dialect of the BASIC programming language.There are both MS-DOS and Windows versions, and two kinds of the latter: Console and Windows.
Error-trapping: allowing BASIC programs to handle unexpected errors via subroutine written in BASIC Conversely, Applesoft lacks the MOD (remainder) operator from Integer BASIC. Adapting BASIC for the Apple II was a tedious job as Apple received a source listing for Microsoft 6502 BASIC which proved to be buggy and also required the addition of ...
