;
; Change History (most recent first):
;
; <SM9> 11/3/92 SWC Fixed the change comment in <SM8>.
; <SM8> 11/3/92 SWC Changed ATalkEqu.a->AppleTalk.a.
; <24> 6/29/92 DTY For ROM and System builds, access IKeyScriptDone through
; ExpandMem.
; <23> 6/25/92 AC When entering passwords, change KeyScript to Roman if RomanOnly
; bit in resource is set. Re-sync selection with actual password
; when entire password gets selected after you've mistyped it.
; (This corrects bugs with two-byte passwords.)
; <22> 6/9/92 JSM Nuke systemCentersWindow conditional, it’s always true.
; Integrate changes from SuperMario: In ROM builds or in TheFuture
; for System builds, use emPPCPromptForUserGlobals instead of
; pGlobals.
; <21> 4/2/92 FM #1020547 The password filter used to hardcode the bullet '•'
; character which isn't internationally friendly. Now I set up the
; bullet character using the itl4 table. The routines to lookup
; the character are now in PromptForUser.c and were written by
; Kevin MacDonell
; <20> 2/11/91 EMT VC,82495: Fix bug that prevents backspacing after 8 characters
; have been typed, Arrow keys now function properly in password,
; Function keys are now ignored.
; <19> 1/14/91 EMT <VC> Fix more bugs in PromptForUser
; <18> 1/4/91 EMT <VC> Fixed bug that caused some items be be partially drawn when
; they are supposed to be hidden. Also found and fixed cursor bug.
; Wrote new efficeint routine MySetCursor.
; <17> 12/13/90 EMT <JSM> Support 0 Length String to mean DefaultPrompt in
; StartSecureSession
; <16> 8/23/90 VC Fixed the handling of "Command-G" in the filter proc. (It was
; checking the wrong bit for whether trhe guest is disbaled.)
; <15> 8/21/90 VC Disabled "Command-G" when guest is disabled.
; <14> 8/18/90 dba get rid of centering, because Window Mgr. does it now; also, I
; noticed a lot of stuff (at least two things) that is not
; internationally friendly, and I marked it with ***; this code
; desperately needs code review
; <13> 8/14/90 VC Added the handling of Command-G and Command-R.
; <12> 8/9/90 S Changed cmdKey to cmdKeyMask (the cmdKey in SYSEQU.A seemd to
; be wrong)
; <11> 8/9/90 VC Implemented the "Command-." option to cancel.
; <10> 5/27/90 JSM Use DCB.B again, now that LinkPatch supports it.
; <9> 5/15/90 VC In CopyPassword, set the string to NIL when the typed password
; is Nil.
; <8> 5/9/90 JSM Don't use DCB.B for pGlobals until LinkPatch supports it.
; <7> 4/26/90 VC Select the proper field after the Callback routine returns.
; <6> 3/26/90 S Fixed the crash of the dialog when guset is selected after a
; connection attemped is failed.
; <5> 3/20/90 S Fix the bug in StartSecureSession to return proper flag when
; guest is selected.
; <4> 2/27/90 S Fix Guest Selection Bug.
; <3> 1/30/90 S Condional Compile for Init and Patch resource IDs.
; 1/22/90 CVC 1.2 Combine PromptAndStart with PromptForUser
; <1.1> 11/28/89 CVC Added PromptAndStart call.
; 11/22/89 CVC 1.1 Added PromptAndStart
; <1.0> 10/12/89 CVC Adding Access Control for the first time.
; 10/11/89 RH 1.0d2 Save registers in the promptForUser routine
; 9/18/89 RH 1.0d1 Added glue code
; 9/15/89 RH 1.0d1 More fixes and changes to displaying code
; 9/6/89 RH 1.0d1 Made changes in the PromptForUser routine to fix bugs when
