I have cases where my defaults "cascade". It's one of the advantages of what I'm doing over the competition.
It's easy to handle on a single card, or when the information is inherited before the card loads, but now I want to make sure that I'm not about to blow my foot off. My cards load all of their values from a database when opened. In this part of the program, the hypercard stack is a more natural way to handle things (and which would probably solve this), but that won't handle the cloud and access from different computers. So card A changes a value which becomes a default for card B. If card B will load with certainty, no problem (well another issue is actually causing the dependent value to save, but solving this solves that). I can set the db value the other field uses, and then send a message to the object that would normally check the default (and use either the default or the override value). Changing this, though, may cascade further, necessitating running scripts on the other card. I can access the name of the card from "word 5 of the long name of the target" (btw: is there a better way to do this?), but having to specify the card of each field reference while operating on that page is just asking to miss one and have a crash-grade bug ship. Do I want to do a "lock screen, push card, send message, pop card, unlock screen"? this seems to solve it if things stay on that crd, but what if it cascades to another? (this is why it too gigahertz class machines for my spreadsheets that do this to be practical--nested lookups on large regions; I think I figured one region was O(4) . . .) Anyway, the snake I see lurking in the grass is if the called card needs to call another. Then it locks the screen again, unlocks it, and, whoops!, the user sees cards popping around. Maybe rather than locking, a lckscrn() and unlckscrn() pair that increment a global counter for this? only actually unlocking when called at depth 1? Or is there an easy way that I'm missing? I thought of changing the default card; if this could be done locally for a routine (like the annoyingly fleeting numberFormat), it would solve it. However, there seems to be no such notion as a default card; just default stacks -- The Hawkins Law Firm Richard E. Hawkins, Esq. (702) 508-8462 hawkinslawf...@gmail.com 3025 S.
