Stephane, please do NOT cross-post the same requests to multiple forums... we heard you the first time.

Thank you.

All of the things you are asking for, technically don't need to be part of PB at all. Instead, you should write your own libraries to do these things in this way. If you ever work with C, you'll see that most things are simply calls to a library. Under the hood, PB does have its own runtime library that drives many functions like print and input. Pascal has that too. Thus the Pascal forms you present are really not faster at all, at least by definition. The conversions you call slow still have to take place. (Numbers have to be parsed from an input string.) The ability in pascal to output a number to a specific decimal place is probably done in a similar way to how PB does it.

As for PowerBasic having too many conversion here and there, remember that the compiler can determine at compiletime the various types of the variables and call the appropriate version of a function. PB has been around a long time, and, if I recall correctly, still has a ton of assembly code in it and probably hand-optimized code. I think it with the exception of dynamic strings (slow by nature) it will out-perform any DOS compiler out there (IMHO).

Hi,

I'm agree but the IDE from de PBDOS is not so professional.
I will see an IDE like Borland Pascal.

Can you writing an routine Write(Ln) and Read(Ln) with input with the
keyboard strings and other datatypes for mee, thanks

Greetings,
stephane

Can you please some from PBVISION/WORKSHOP????

I really do not know what you are asking. If the pascal program did:

WriteLn("Enter your name: ")
ReadLn(age)

then in PB, you could do:
Print "Enter your name: "
Input age

or

Input "Enter your name: ",age

If you want a C-style, formatted print or input, then that's a lot more complicated, although PB seems to do fine with print and input.

In your first post you already have examples of this. What are you looking for? Please give us more information.

Hi,

Can you please give your emailadres to me then can I writing an
email for the problemdefinition about new statements for
PowerBasic:
Name statement : input to the keyboard Read and ReadLn
Syntax : DECLARE SUB Read(BYVAL variabele of datatypes) I think
Function: User input an digit or an string in the variabele
DIM a AS STRING
DIM digit1 AS BYTE|WORD|INTEGER|DWORD|QWORD...
DIM digit2 AS SINGLE|DOUBLE| ==> floats

Read(a) ===> user type this is testing
Read(digit1) ====> user type 124 or 64000 or -4514 or...
Read(digit2) ====> user type 45.4512 or 12.4512E15 or...
Read statement :reading the variabele and control datatype en formatting
Readln is with CR/LF

Name statement : OUTPUT to the screen Write en WriteLn

Syntax : DECLARE SUB Write[Ln]() I think
Formattype is for formatting integers, strings, floats
for integers : only the position parameter
for floats: the position and the fraction parameter
Of is that possible formatting like C ==> printf("testing getal %d",digit)????

Function:

DIM A AS INTEGER
DIM B AS SINGLE

A = 4578
B = 45141.451781

Write "this is an digit %d", a =======> 4578
Write "This is an digit %f3.2", b =====> 451.45

WriteLn is with CR/LF is the same function

Can you please written this code in PB for me in Assembly or PB?
Its for using in PBDOS en PBCC

Thanks,
stephane

How about using the native functions that PB/DOS already contains for string and number formatting...

Code:

PRINT "this is an digit " + STR$(a)
PRINT USING$("This is an digit ###.##", b)

Stephane,

Well I just had to get into this, I really don't know why??

With a little simple programming on you part, you can do the
same thing that your PASCAL code is doing.

What I am showing you is knowing more than doing some programming
for yourself. The functions you use in PASCAL will create as much
code or more in the final program. I have written programs in
PASCAL, as far as I'm concerned it is out dated.

I spent about 30 minutes of my time, start using some of yours.
By the way, I charge 150.00 US for my time.

' This code was written in PBCC, compile it with PBCC

Code:

DECLARE FUNCTION PxGetMONEY$ (BYVAL a##, BYVAL chars&, BYVAL DEC&, BYVAL fchr&)
'  A## will accept any %,!,#,@ value passed to it
'  PowerBasic Code will Convert A!, or A as single to A##
'  chars& = width of string returned RIGHT JUSTIFIED
'  DEC& = Number or Decimal Placing to Use
'  fchr& = Fill character for blank space.  Normally 32 for space

FUNCTION PBMAIN() AS LONG
  a%=4578
  PRINT PxGetMoney$(a%,10,0,32)
  PRINT PxGetMoney$(a%,10,2,32)
  a!=45141.451781       ' this value doesn't meet the requirements of single
  PRINT PxGetMoney$(a!,10,0,32)
  PRINT PxGetMoney$(a!,10,2,32)
  a#=45141.451781
  PRINT PxGetMoney$(a#,10,0,32)
  PRINT PxGetMoney$(a#,10,2,32)
  PRINT PxGetMoney$(a#,10,4,32)
  a##=4514145141.451781
  PRINT PxGetMoney$(a##,20,0,32)
  PRINT PxGetMoney$(a##,20,2,32)
  PRINT PxGetMoney$(a##,20,4,32)
  a&=141451781
  PRINT PxGetMoney$(a&,20,0,32)
  PRINT PxGetMoney$(a&,20,2,32)
  PRINT PxGetMoney$(a&,20,4,32)
  a&&=141451781
  PRINT PxGetMoney$(a&&,20,0,32)
  PRINT PxGetMoney$(a&&,20,2,32)
  PRINT PxGetMoney$(a&&,20,4,32)
  [email protected]@=141451781.4578
  PRINT PxGetMoney$([email protected]@,20,0,32)
  PRINT PxGetMoney$([email protected]@,20,2,32)
  PRINT PxGetMoney$([email protected]@,20,4,32)
  [email protected]@=141451781.4578
    ' do some check writing   
  PRINT PxGetMoney$([email protected]@,20,2,42)
  
  

  LINE INPUT kk$

END FUNCTION

FUNCTION PxGetMONEY$ (BYVAL a##, BYVAL chars&, BYVAL DEC&, BYVAL fchr&)
   LOCAL c$,rsp$
   SFORMAT$ = "########################": IF fchr& = 0 THEN fchr& = 32
   IF DEC& THEN SFORMAT$ = SFORMAT$ + LEFT$(".##########", DEC& + 1)
   rsp$=RIGHT$(SPACE$(LEN(Sformat$))+FORMAT$(a##,sformat$),LEN(sformat$))
   IF DEC& AND (VAL(rsp$) >= 0 AND VAL(rsp$) < 1) THEN
      rsp$ = SPACE$(24) + RIGHT$(rsp$, DEC& + 1)
   END IF
   c$="":IF fchr&=42 THEN c$="**"
   PxGetMoney$ = RIGHT$(STRING$(chars&,fchr&)+LTRIM$(rsp$), chars&)+c$
END FUNCTION
