Examples / bastest Bas BASIC Tests
This directory contains a small program that will mount a ROMFS file system
containing the BASIC test files extracted from the BAS 2.4 release.
Background
Bas is an interpreter for the classic dialect of the programming language BASIC. It is pretty compatible to typical BASIC interpreters of the 1980s, unlike some other UNIX BASIC interpreters, that implement a different syntax, breaking compatibility to existing programs. Bas offers many ANSI BASIC statements for structured programming, such as procedures, local variables and various loop types. Further there are matrix operations, automatic LIST indentation and many statements and functions found in specific classic dialects. Line numbers are not required.
The interpreter tokenises the source and resolves references to variables and jump targets before running the program. This compilation pass increases efficiency and catches syntax errors, type errors and references to variables that are never initialised. Bas is written in ANSI C for UNIX systems.

OPEN file locking
Test File
on error goto 10
print "opening file"
open "/tmp/test.out" for output lock write as #1
print "open succeeded"
if command$<>"enough" then shell "sh ./test/runbas test.bas enough"
end
10 print "open failed"
Expected Result
opening file
open succeeded
opening file
open failed
Notes
- The logic in this test will fail opening the test.out file if there is no
writable file system mount at
/tmp. - This test will still currently fail when try to fork the shell because support for that feature is not implemented. The following error message should be received:
Error: Forking child process failed (Unknown error) in line 5 at:
if command$<>"enough" then shell "sh ./test/runbas test.bas enough"
