- WS4/System setup:
- ZCPR3 installation & WS configuration
- All WS .com, .ovl files on the path
- current directory is NOT on the path
-
- Problem: If memory contains 0FFH at address 2201H, then WS
- invocation results in 'can't find WS.OVR' error msg.
-
- If memory at 2202H contains a non-existant drive code
- (A=1, 16h=P) then a ZRDOS error #2 occurs. This would probably
- also produce a BDOS error.
-
- These two bytes clearly are storage for User/Drive for the WS.OVR
- file. After a successful invocation of WS4, they contain the
- correct DU for the WS.OVR file.
-
- WS.COM loads from 100H to 1BFFH. The memory locations above
- are not part of the WS.COM image. WS apparently initiates its search
- for the .ovl file using the DU found in this location; if the drive
- does not exist there is a problem. If the User number initially
- present is allowed, then the search starts there and continues
- using the path (either built-in or the ZCPR3 path?). If the High bit
- is set (user # >7fh) then the search for WS.OVL fails forthwith.
-
- A null value in both locations causes no problem; the path
- search is completed successfully.
