Upgrade a Pascal cashbook to run on W2000/xp

A client of mine has asked me if I can find somebody to upgrade his Pascal Cashbook to run under windows 2000 & XP. I have heard this only needs recompiling?? The cashbook is to hold details of his clients taxes and (I belive) probably first ran underw95 or even 3.1. I really need to know how much something like this may cost - sorry about being vague - its kinda 3rd hand. Tell me what you need to know and I'll try to get more information. (Turbo Pascal 5 seems to spring to my clients mind) ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Complete ownership and distribution copyrights to all work purchased. ## Platform It is to run under W200/XP - currently works on 95 & I believe 98 (need to check) ## Deadline information I am in the UK
