Hello,

My Question:
Is there a utility, (either HMG Official or HMG Extended), that can examine a .PRG and identify either:
A variable used but not declared
OR
A variable declared but not used
============================
Google Spanish:
¿Hay alguna utilidad, (ya sea HMG oficial o HMG extendida), que pueda examinar un .PRG e identificar:
Una variable utilizada pero no declarada
O
Una variable declarada pero no utilizada

Thank you for your kind help,
Red2

Hello Red2,

It is possible with using Harbour switch -w3, i.e.

Hi Gregory,

Thank you for your prompt answer.
I certainly will investigate your kind suggestion.
Thank you so much!

So far I have only worked using the IDE.
(In VFP I had utilities to find undeclared and unused variables).

i use a *.HBM File to call Compiler Option

Code: Select all

your.hbc 
-w3 -es2

Hi Jimmy,

Thank you for your kind suggestion.
I think I need a little more help.

Do I create a file named <MyProject>.HBM where I include the code you suggested?
Does this new file do into the <MyProject> directory?
Then in the HMG IDE do I "Reset Project Incremental Data" and then simply compile?

Thanks again!

Hi All,

I downloaded Harbour via Gregory's link, https://harbour.github.io/
I then installed it into C:\HB32\. Harbour is now installed

I attempted to follow the "suggested" syntax (above) using:

Code: Select all

C:\HB32\Harbour DataBrowse_OnInit.PRG -n -w3

I keep getting Error F0029 Can't open #include file .....ch
So, I went into "Environment Variable" then "Edit environment variable" dialog and added to my Paths:
C:\HMG3.Include
AND
C:\MiniGUI\Include

Apparently these Path additions do not resolve these ....ch files errors.
Those of you with Harbour experience, could you kindly advise me here?
This is brand new territory to me.

Thank you,
Red2

hi Red,

i use *.HBP which include all *.PRG of the Project
i use *.HBC which include all Libs=myLib
i use *.HBM which include Compiler Option like -w3
all are in Project Folder

dblclick on *.HBP will ask "how" to handle it so assign it to your IDE EXE (Unicode or ANSI)
later you "just" Dblclick on *.HBP to "load" Project into IDE

All this is also very new to me....
Learning each day!

If you're using IDE, you can add this line to Configuration tab:
prgflags=-w3

After compilation, you can look for build.log in your project folder to see all warnings

Hi All,

Thank you, Gregory, Jimmy, and Mol, for your generous advice and suggestions.
I am building using the "Official" HMG IDE. So far I's getting back no warnings.

My Problems:
1) From the command prompt Harbour's (C:\HB32\bin\Harbour DataBrowse_OnInit.PRG -n -w3)
only generates a series of messages like: Error F0029 Can't open #include file 'hmg.ch'.
I have no idea what is occuring here.

2) I created a HBM file containing prgflags=-n -w3 in my Project directory.
Unfortunately the "build.log" contains no information on variables.

3) What would the "Configuration tab" be in the "Official" HMG IDE?

May I please request further guidance. Thanks again!
