BAS2SB - BASIC to Structured BASIC Converter

Program Information


BAS2SB automates many of the source code re-formatting
procedures commonly performed when switching over from
BASICA or GW-BASIC to the new generation of BASIC
compilers (such as Turbo BASIC or QuickBASIC).

BAS2SB programs become much more comprehensible, and as
a result, much simpler to convert into structured
formats. This will allow you to take full advantage of
QuickBASIC or Turbo BASIC.

BAS2SB uses a BASIC source code file (ASCII format) as
its standard input, and returns a newly formatted
program that includes:

1) One statement per program line
2) IF, THEN, ELSE Nested Indentation
3) END IF blocked structures
4) Removal of non-targeted line numbers
5) Replacement of targeted lines with either
program generated, or user-supplied labels


Don't expect to recognize your new programs immediately.
BAS2SB does NOT alter variables or actual code, but
linear programs with meaningful line labels take time to
adjust to. It is highly advisable to have a hard copy
of the original (numbered) source code at hand while
adding mneumonic labels. Each target line can then be
respresented by the function it performs. You will
probably find this approach is worth the extra time,
since it must be performed only once.


BAS2SB needs very little assistance in converting BASIC
programs. Listed below are the only requirements:

1) Program must be in ASCII format (save with ",A").
2) Program lines must NOT contain any line-feeds or
other control characters.
3) Program lines must not exceed 255 characters.
4) Program source file must have a .BAS extension.

BAS2SB does NOT alter the original source file.
Instead, another file with the extension .SBX is created
that will run under QuickBASIC and Turbo BASIC.


When invoking BAS2SB, you will be prompted for a
filename. Do NOT include an extension - the only one
allowed is the default, .BAS.

If the source file is located, BAS2SB will begin to
reformat the source file by looking at each line
individually and will present each target line number
and a prompt for an optional label.

When prompted, you may choose to:

1) Enter a line label (up to 20 Characters).

2) Enter a RETURN. (BAS2SB will provide the label).

3) Enter a period. From that point forward, BAS2SB
will provide target labels.

The number listed on the LEFT side of the display is the
source line number being examined.

The number (if any) on the RIGHT side of the display is
the target line number that was found in a corresponding
GOTO, GOSUB, THEN, ELSE, etc. Once a target has been
labeled, further references to that target will be
automatically replaced without user intervention.


In the case of ERL references, BAS2SB will retain the
original line number references in the newly generated
source file. This allows proper trapping through the
use of the IF ERL construct.


BAS2SB performs no error checking. Any BASIC program
that compiles correctly BEFORE conversion should compile
correctly AFTER conversion. BAS2SB will not fix
programs that do not run.
