Technical Highlights

Overview

Basmark QuickBASIC is a multi-user Microsoft

QuickBASIC and IBM-PC BASICA compatible

Compiler for Unix (e.g. AIX, Solaris, HP/UX, SCO

Unix and Linux), optimized to provide consistency and

high performance across various machine architectures.

Multi-user enhancements include file sharing with file and

record locking, TERMCAP/TERMINFO screen handling

and inter-process communication via PIPE:.

Basmark QuickBASIC accepts source files to produce

assembly and object languages of the host machine. This

provides source code security not provided by traditional

interpreters. Since a high performance, extremely efficient

run-time module is produced, execution speed is much

faster than an interpreter and native floating point

instructions are generated to maximally utilize the

hardware.

Basmark QuickBASIC is a highly transportable

language compiler that, with the exception of certain

hardware dependent features and various QuickBASIC

commands inconsistent with a multiple machine

environment, will perform identically on different

multi-user, interactive systems. Thus, the very large base

of application programs written in QuickBASIC is now

available across a wide range of machines simply by

recompiling.

Basmark QuickBASIC supports the use of real,

seperately compiled subroutines (that can use local and

global variables) and multiple modules with shared,

labeled COMMON blocks. Object modules can be

linked together to created large programs that use

available memory.

Basmark QuickBASIC provides structured

programming facilities to simplify program logic and

increase both readability and maintainability.

Basmark QuickBASIC's extensive run-time library

provides the arithmetic functions, file handling routines and

string handling functions of QuickBASIC. Full run-time

error messages are provided that aid the programmer in

the diagnosis and correction of programming errors.

Basmark QuickBASIC comes with a complete set of

user documentation, including user's guide, reference

manual, error messages and a complete description of the

run-time library. An electronic version of the

documentation (HTML /WEB format) is forthcoming.

There are two current releases of Basmark QuickBASIC, 3.7 and 4.9. The syntax flagged with an asterisk is not available

in version 3.7. Version 3.7 is most appropriate for compiling older MBASIC, BASICA and QuickBASIC 2 or 3 programs.

NAME

basic - Basmark QuickBASIC compiler

SYNOPSIS

basic [ option ] ... file ...

DESCRIPTION

Basic is the Basmark QuickBASIC compiler from

Basmark Corporation.

Basic accepts several types of arguments:

An argument whose name ends with `.b' is taken to be a

BASIC source program; it is compiled, and the object

program is left on the file whose name is that of the

source with `.o' substituted for `.b'. The `.o' file

is normally deleted, however, if the BASIC program is

compiled and loaded all at one go.

The first file is taken as the main module where execu-

tion begins. If the file is a BASIC source program, a

startoff is included in the object program.

The following options are interpreted by basic.

See ld(1) for load-time options.

-v Print compiler version number and messages

identifying compiler passes as they occur.

-c Suppress the loading phase of the compilation,

and force an object file to be produced.

-S Compile the named BASIC program, and leave the

assembler-language output on the corresponding

file suffixed `.s'.

-o " output" Name the final output file output. If this

option is used the file `a.out' will be left

undisturbed.

-m Merge all upper-case alphabetic characters into

their lower-case counterparts, except upper-case

characters appearing in DATA statements and in

literal strings. This option must be used if the

BASIC source file is entirely in upper-case;

otherwise, the BASIC reserved words will fail to

be recognized.

-K Do not generate code to support chaining at run-

time. No module compiled with this option may

participate in chaining. This flag can be used

to save space in the object module.

-G Maintain information at run-time about line

counts instead of line numbers for tracing and

error recovery. A line count is the number of

physical lines in the source file (including

lines for include files) starting with one.

This is useful in producing diagnostics for

programs with few line numbers. This flag is

overridden by the -L flag.

-L Do not generate code to maintain information at

run-time about line numbers for tracing and

error recovery. This flag can be used to save

space in the object module and to decrease

execution time.

-C Do not generate code to check for out-of-bounds

subscripts at run-time. This flag can be used to

decrease execution time.

-R Store arrays in row-major order. Normally, they

are stored in column-major order.

-Idir Secondary location for include files. Filenames

given by the $INCLUDE meta-command which do not

begin with / are searched for first in the

current directory and then in the dir directory.

-M No main module. Do not generate a main module

startoff for any file. This flag facilitates

separate compilation.

Other arguments are taken to be loader option arguments.

The environment variables BASHOME and BASTEMP are used to

override default assignments for the directory where the

compiler passes are located and the directory used for

temporary files, respectively. The defaults for these

directories are /usr/lib/basic and /tmp.

For Version 4.9 ONLY

The compile time options `-m', `-M', `-C', `-K', and `-R'

are no longer required. As in previous releases, the

symbol table is not stripped from executables and passing

the `-s' flag to the Unix loader via the basic command line

or explictly using the Unix `strip' command) is strongly

recommended to decrease the size of executable files.

Version 4.9 performs optimizations on generated code if

the new compile time option, `-O' is specified on the

command line.

Version 4.9 generates executable programs which ignore

the interrupt and quit character (signals). This was

changed from earlier releases due to popular demand.
