The development notes for GibPascal 1.3.2(Alpha)

Here is what has been completed:

o corrected windows compile version

o rewrote the block processing to be more flexible.
for program, var, const, label, begin, and end.

o Now MS Windows detection is on the list of supported Operating Systems
As of new version has not been introduced for Windows

o allow space between ',' and var (or no spaces) in write / writeln... read more

I have wrapped up the 1.3.1 code. This is a mostly fix release with a few added features.

The development notes for GibPascal 1.3.1(Alpha)

Here is what has been completed:

o add new file writing logic and code
+append
+fileclose

o corrected some debug errors

o fixed exec and system function commands with a code rewrite.

'while .. do' loops have been added to the GibPascal 1.3 release.

Usage format is as following:

[while [variable]|[count]|[<|>] [value] do begin ... end]

Here is an example of the 'while .. do' using a variable:

loop1 := 5;
while loop1 < 10 do
begin
loop1 := loop1 + 1;
loop2 := loop2 + 2;
writeln('loop1 = ',loop1,' loop2 = ',loop2);
end;

This example would run the three internal loop statements 5 times.... read more

Still writing code for the next release. Since the last post:

o corrected issues with delete function.

o corrected issues with right side variables with until statement.

o More variable fixes have been applied.

o 'while' ... 'do' ... 'begin' ... 'end;' coding has started. basic constructs have been done.
Basic for loops are working.
Nesting of for loops and var manipulation still has much work.... read more

The development notes for GibPascal 1.3 (currently Alpha)

Here is what has been completed:

o Added -lm flag to all compile scripts

o Made most functions not case sensitive.
Example: 'WriteLn', 'WRITELN', and 'writeln' are all treated the same.
Variables and reserved words continue to be case sensitive.

o Altered/expanded Math_set further.

o Now halt is POSIX in that 'halt;', 'halt(0);', and 'halt(1);' are all now valid
Any other value other than none, 0, or 1 will be ignored and return 1;.... read more

Just an FYI. GibPascal1.2 will not currently compile on Linux without adding the -lm flag to the compile shell scripts. This will be fixed in the next release.
