Re: HyperCard Porting
Thanks for all your answers! The crashing occurs at opening... Some open just fine, while some stacks crash just when opening them. AddColor has not presented a problem other than an error. I believe that scripts in AppleScripts language could cause the problem but must be verified. Calls to XFCNs or XCMDs are simply or usually error prompted. Script differences from HC only report errors which are easy to fix but do not crash MC. I'll try to compact stacks before opening them but I doubt it will work since MC probably needs to open them before compacting. Otherwise, I'll have to find more room in my office for my old mac! thanks again! I am afraid you may have to dig out your Mac after all or ask someone else to compact them for you -- the compacting must be done by Hypercard (it is a process by which HyperCard removes obsolete data). By the time MC has a chance to do compacting, it has already converted the stack. I can concur with experience of others that compacting drastically reduced conversion problems.

Re: HyperCard Porting
you can put an autocompact handler in your hypercard stacks... on openstack end openstack on closestack end closestack You can even put handlers like this into your home stack , i.e. with clever scripting you should not need to put these handlers in each and every stack - though I would recommend doing so! I never need to do this so I do not know what the command is - is just pseudo code but you can definitely tell a hypercard stack to compact itself.

FWIW, I've never knowingly compacted a stack before importing it - and never
seen a problem caused by this - but it can't hurt!
The various syntax issues, which can take a little while to track down, are
a pain but have not in my experience led to crashing.
All the crashes I've had have been to do with XCMDs. MetaCard supports the
original HyperCard XCMD protocol; many many XCMDs were built to the later
("HyperCard 2") era protocal, and assume the use of callbacks that aren't
supported by MetaCard. It is possible in principle for an XCMD to be
written in a way that tests for the existence of the callbacks it attempts
to use - very few, I suspect, were written in such a way. Certainly none of
the ones I wrote!
I would look for XCMDs as the cause of the crash before I'd look for
anything else. You might for example make a copy of the stack with all
resources stripped, and try running that; my expectation if the XCMD was the
problem was that you'd get an error message about an undefined function, at
approximately the same point (or possibly before) as you previously crashed.
If you do find the problem is a crashing XCMD, you have two choices: recode
the functionality in MetaTalk, or fix the problem with the XCMD. If at all
possible, even if you have access to the source code of the XCMD, I
recommend you do the former. You gain portability, flexibility, and
frequently speed (especially if the XCMD is a 68K one).
Good luck,

HyperCard Porting
Hi everyone, Im porting a lot of stacks from HC on MC for PC. Unfortunately 30% are crashing MC which is quite hard to swallow. Does anyone have any tips? I really dont want to dig out my old mac from the basement as I have no more room in my office!!!
