I'm sure *someone* must have written one... I don't know of any PD ones. "Turbo Technojocks Toolkit" has promised one for later this year, as shareware. I was unimpressed with their library when I looked at it last year; I don't know what current or future versions will be like. Your best bet is the Object Professional library, from Turbopower. Typical mail order price is $US 119, from Programmer's Connection(800-336-1166 in USA, 800-225-1166 in Canada, 216-494-3781 elsewhere). It comes with full source code and lots of tools (with full source for them, too). The most negative thing about it is its size: it takes about 10 Megs of disk space to install it, and if you use any of the high level objects (data entry screens, text editor, etc.) your programs really bloat, and TP5.5 has trouble linking them. (It will link them, but it's slow, and you have to use TPC, not the IDE.) Here's a list of the units provided (cut from the memory resident help utility, POPHELP): Op8087 OpAbsFld OpAsciiz OpBcd OpBrowse OpCal OpCalc OpClone OpCmd OpColor OpCrt OpDate OpDevice OpDir OpDos OpEdit OpEditor OpEms OpEnhKbd OpEntry OpErrHan OpExec OpExtMem OpFEdit OpField OpForm OpFrame OpHelp OpInline OpInt OpLArray OpMacEd OpMacro OpMemo OpMenu OpMouse OpPick OpPrint OpPrnLow OpQkRef OpReplay OpRoot OpSEdit OpSelect OpSort OpStrDev OpString OpSwap OpSwap1 OpTsr OpWindow and a list of the object hierarchy from the low-level unit, OpRoot: Root PointerStack StaticQueue SingleListNode SingleList DoubleListNode DoubleList CircularList BitSet LargeBitSet StringDict StringSet StringArray The ones below have to do with streams - all objects can be written to streams. DirEntry IdStream DosIdStream BufIdStream Library MemIdStream MemLibrary Because the library is so big, I'd hesitate to recommend it as a general purpose library. Turbo Professional from the same company is better for that. However, if you want to use OOP, and don't want to program all the low level stuff, I'd buy it. Treat all the extras as a bonus. I have no connection with Turbopower, other than as a satisfied customer. Duncan Murdoch dmurdoch@watstat.waterloo.edu
