Here's some things Rascal programmers might like to fix in their
libraries.
in uToolIntf:
The KeyMap type is defined as Byte[8]. Should be Byte[16]. Guaranteed
to crash otherwise.
in __DeskLib:
The GetResIDBase function has a line that says
if !IsDARun then ...
Since IsDARun is a function, one wants to test its value, not its
address. Replace with
if !IsDARun () then ...
in __ToolLink:
TEFromScrap has a line that says
L := GetScrap (TEScrapHandle(), ptrl (" TEXT"+2)^, 0L);
That "0L" parameter is supposed to be the address of a long variable,
into which an offset is placed. 0L will work, coincidentally, but
isn't really correct. It will also mess up techniques such as early
detection of nil pointers by placing -1L at address zero (this is used,
e.g., in some of the Skels posted to the net a while back).
Fix: declare a LongInt variable offset, change above line to:
L := GetScrap (TEScrapHandle(), ptrl (" TEXT"+2)^, @offset);
