1. Additions to EDS (ATTN Rob)
Rob,
I've added the following because they serve my needs right now. If they are
already implemented, please let me know! Thanks...
global function list_db_names() -- quick list of open databases
return db_names
end function
global function db_current() -- return name of current database
return db_names[ find( current_db , db_file_nums ) ]
end function
Need your help wit' this one:
global function db_current_table() -- return name of current table
-- ???
end function
If you could provide this function for me, I'd appreciate it.
Thanks!

You could simply record the name whenever you call
db_select_table(name).
Or, you could use the value of current_table
to get the name, something like:
-- warning: untested code taken from table_find():
safe_seek(current_table)
name_ptr = get4()
safe_seek(name_ptr)
name = get_string()
This might break if the data structures are ever changed.

I am in the process of writing an on-line front end to EDS with a few extra
facilities (built into the calling code rather than DATABASE.E). However I
did add the following code to DATABASE.E which may be of use:
global function db_return_currentdb()
sequence db_return
integer current
if current_db > 0 then
current=find(current_db,db_file_nums)
db_return=sprintf("%s",{db_names[current]})
else
db_return="No database open"
end if
return db_return
end function
global function db_return_currenttable()
sequence db_return
object current
integer pointer
if current_table > 0 then
safe_seek(current_table)
pointer = get4()
safe_seek(pointer)
current = get_string()
db_return = sprintf("%s",{current})
else
db_return = "No tables current"
end if
return db_return
end function
global function db_return_alldbworking()
sequence db_return
db_return={}
if length(db_names)>0 then
for count = 1 to length(db_names) do
db_return = db_return & sprintf("%s",{db_names[count]})
if count<length(db_names) then
db_return = db_return & ','
end if
end for
--? db_return
--key=wait_key()
else
db_return="No databases loaded"
end if
return db_return
end function
global function db_return_alldb()
object db_return
db_return={}
if length(db_names)>0 then
for count = 1 to length(db_names) do
db_return=db_return & sprintf("%s",{db_names[count]})
if count < length(db_names) then db_return=db_return & ',' end if
end for
else
db_return="No databases loaded"
end if
return db_return
end function
If they are useful please feel free to adopt/change/ignore. I will post the
on-line front end in a few weeks.
