Änderungen von Version 0.6 zu Version 0.7:
|
||||
Änderungen von Version 0.6 zu Version 0.7:
|
||||
Das DCS-Window wurde implementiert, dadurch wurde auch ein Unterschied zwischen "Beenden" und "Basic" eingebaut (Bei ersterem erfolgt die DCS-Abfrage).
|
||||
Die Strings der Windows liegen jetzt nicht mehr als Screencodes vor, sondern als PetSCII-Werte; die Routine ".makewin" konvertiert dies also.
|
||||
Die Bedeutung des Flags "unnamed" wurde invertiert.

10.10.1998: Ersetzen von "{" und "}" in Labels durch "_" und "__"
|
||||
12.10.1998: Unterschiede zu v0.6 dokumentiert.

3.11.1998: Label "notmany!" durch "notmany" ersetzt. Wo kam das bloß her ?
|
||||
4.11.1998: Zwei fehlerhafte Auskommentierungen entsorgt. Die Stellen wurden mit "**mark**" gekennzeichnet. Wo kam das bloß her ? Außerdem wurde "< = >" in einem Textstring wieder zu "<=>" korrigiert. Das ist wohl beim automatischen Layout passiert.
|
||||
4.11.1998: Top-Bit-Set-Zeichen aus Textstrings enfernt und byteweise eingefügt, z.B. auch "Cursor up/down/left/right"-Werte. Außerdem alle Filenamen angepaßt.

|
||||
27.11.1998: Aufeinanderfolgende "!tx" und "!by" gemerged, BIT-Trick benutzt, Hexzahlen auf lowercase gebracht, Binärzahlen auf Spezialformat gebracht, Einrückungen dezimiert, Zahlen durch Label ersetzt, "firsttry" in "repeatedtry" umbenannt (war vorher unlogisch).
