Tasty Basic Files

Introduction

The CP/M version of Tasty Basic allows programs to be saved to and loaded from disk. This document describes the Tasty Basic .TBA file format.

.TBA File format

Tasty Basic .TBA files are direct reflections of Tasty Basic programs as held in memory. Thus, each line of code starts with a 16 bit, LSB first, line number and ends with a carriage return character (0xD). An EOF marker (0x1A) indicates the end of the file. Any trailing NUL characters (0x0) are ignored.

Example

Following is an example Tasty Basic program:

10 PRINT "HELLO WORLD"
20 GOTO 10

And its .TBA file representation:

0A 00 50 52 49 4E 54 20 22 48 45 4C 4C 4F 20 57 
4F 52 4C 44 22 0D 14 00 47 4F 54 4F 20 31 30 0D
1A 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
