Packed array (strings) update
by loop lopy 12 Mar '05

12 Mar '05

I have changed the string to start from 1: String = packed array[1..256] of char; var Test:string; begin readln (Test); end. Now I get the following error: ISO 7185 Pascal does not allow reading strings from textfiles So, how am I suppose to read a string? Read a char one after another? Another question, how do I mark the end of string? Is there a special char for that, like '/0' in C? __________________________________ Do you Yahoo!? Yahoo!

Packed array (correction)

It suppose to be: String = packed array [0..255] of char; __________________________________ Do you Yahoo!? Yahoo! Small Business - Try our new resources site! http://smallbusiness.yahoo.com/resources/

In order to read strings I have defined the following type: String: packed array[0..255] of char; However, when I have the following code: var Test: String; begin readln (Test); end. I get the compil error: only packed array of char may be read from 'Text' files How should I read a string with readln? __________________________________ Do you Yahoo!? Yahoo!

String type

It seems there is a string type in turbo pascal. Howver, in gpc it gives a compiler error if something is defined : String; So, there is no type string in gpc --standard-pascal? How do I read a string from the input? I need to use readln? I need to use a Text type variable or is there a predefined variable of text type that is used for standard input? How do I use readln? __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com

Compiling errors
by loop lopy 12 Mar '05

I omitted the additional type and the first compilation error has been removed. Now I have two additional compilation errors. My code is: program Ex1 (input, output); type NumNode = record Value: integer; pNext: ^ NumNode; end; nNumber = record DigitsAmount: integer; DigitValue:^ NumNode; MSD: integer; DigitBase: integer; end; function nNumberIsEmpty (Num: nNumber): boolean; begin nNumberIsEmpty := (Num.DigitValue=0); end; function nNumberPop (var Number: nNumber): integer; var pNextValue:^ NumNode; begin if (nNumberIsEmpty(Number)) then nNumberPop:=0; else begin Number.DigitsAmount:=Number.DigitsAmount-1; pNextValue := Number.DigitValue^.pNext; dispose (Number.DigitValue); Number.DigitValue:=pNextValue; if (Number.DigitsAmount=0) then begin Number.MSD:=0; nNumberPop:=0; end else begin nNumberPop:=pNextValue^.Value; end; end; end; function nString2nList (String:^ char; var Number:nNumber;):boolean; begin end; begin writeln ('Hello world'); end. The errors I get: ex1.pas: In function 'Nnumberisempty': ex1.pas:17: invalid operands to binary = ex1.pas: At top level: ex1.pas:44: parse error before '^' What causes these errors? --------------------------------- Do you Yahoo!?

I have the following code: program Test (input, output); type Num1 = record Value: integer; end; type Num2 = record Value: integer; end; type Num3 = record Value: integer; end; function a (b:integer): integer; begin end; begin end. I get the following errors: test.pas:11: wrong order of declarations according to ISO 7185 Pascal test.pas:15: wrong order of declarations according to ISO 7185 Pascal How do I fix this? --------------------------------- Do you Yahoo!?

Wrong order of declaration

If I write the following code: program Ex1 (input, output); type NumNode = record Value: integer; pNext: ^ NumNode; end; function a (b:integer): integer; begin end; begin end. Then the compilation works. So it seems the second record is somehow not accepted. --------------------------------- Do you Yahoo!? Yahoo! Small Business - Try our new resources site!

Wrong declaration order

Hello Here is my code: program Ex1 (input, output); type NumNode = record Value: integer; pNext: ^ NumNode; end; type nNumber = record DigitsAmount:integer; DigitValue:^ NumNode; MSD: integer; DigitBase: integer; end; function a (b:integer): integer; begin end; There is nore code, but I dont think it is needed to understand what causes the compiler error. What might cause this compilation error? P.S.: I didnt see where I can turn off HTML email. --------------------------------- Do you Yahoo!? Yahoo! Mail - Easier than ever with enhanced search.
