Long strings in Delphi 1.0

We have a massive app written in Delphi 2.0 which uses a lot of VERY long strings.  Now we have to re-do it for Delphi 1.0.  It seems that we must contrive a custom class for handling strings of arbitrary length, longer than Delphi 1's limits.  Others must have faced this.  How is it done?  Deeply appreciate any help.

You might have to use PChars.

That's a bad way - downsourceing.

Strings where different handled in Delphi 2.x and 1.x, therefore:

If you want to have all the easy to handle string-handling-routines, the best way may be to build a new string-class in Delphi 1.x which supports all this functions.

If you've only used ANSI-string routines in delphi 2.x, you can change alle string statements into PChar-statments.

Both possibilities are not done without any changing of code.

There may be some string-classes for Delphi 1.x on some web-sites, like Delphi Super page.

tfwong:  Thank you for your interest.  Your question, "How Long":  Answer:  Arbitrary length, generally much longer than the 65K limit in Delphi 1.0.  Do you know the URL for Delphi Super page?

buemoh:  Thank you for your interest.  Yes, I have to "build a new string class" in Delphi 1.  How is this done?  If you can help me, you can have the 100 points.  -- Norm

Why not setup a new type called lstring and make it an array or characters?  Or use PChar.  They are easy to use.

If you are concered about the 64k limit, make a pointer, use getmem and the size you will need and point a pointer to it.  Then you can reference the string and it can be as long as you need it.
