Magic PDM

The Personal Data Manager (PDM) is designed to provide
a simple, easy-to-use method of defining, maintaining, and
retrieving user information.
A user may create as many PDM files as desired. However,
all PDM files must reside on the Magic: diskette. A PDM
file consists of up to twelve fields; each field contains
up to 40 characters of data. To conserve screen space, all
fields scroll horizontally in independent, 25 character
boxes. All fields may be named by the user.
Fields are updated by selecting (with the left mouse
button) a particular field's box. A cursor will appear
in the box and the field may then be edited. The arrow
keys, backspace key and delete key may be used. Pressing
RETURN or selecting another field ends the field update.
Errors and informative messages are displayed at the
bottom of the PDM window.
All actions are controlled by PDM's two menus
(controlled by the right mouse button).
The first menu controls file operations. The FILE
OPTIONS are:
1) CLEAR DISPLAY -- clears the entire PDM
display in preparation for other file
operations (such as creating a new file
or specifying which file to use).
Changes all field names to "FIELD 1" thru
"FIELD 12". Closes any currently active
file.
2) USE FILE -- opens the PDM file specified
in the "FILE" box and changes the field
names accordingly.
3) CREATE REPORT -- creates a report of all
records in the currently open file.
The report file is named:
Magic:<filename>.rpt
where <filename> is the name of the file.
4) CREATE FILE -- creates a new PDM file.
The name of the file is taken from the
"FILE" box; field names are taken from
the "FIELD n" boxes. Extra fields may
have a blank field name.
5) CHANGE FILE -- changes field names in
the currenly active file. Any non-blank
boxes are assumed to be replacements
for the corresponding field names.
6) DELETE FILE -- deletes the currently
active file.
The second menu controls record operations. The RECORD
OPTIONS are:
1) CLEAR DISPLAY -- clears the field boxes
in preparation for other record
operations.
2) FIND RECORD -- finds the first record
in the currently active file whose data
matches that specified in the field boxes.
Blank boxes are ignored in the search
(implying that invoking this operation
with all blank fields will return the
first record in the file). Multiple
field specifications are assumed to be
ANDed together.
3) NEXT RECORD -- finds the next record
in the currently active file whose data
matches that specified for the last
FIND RECORD command (see above).
4) SPEAK RECORD -- will speak the current
record (field name followed by field
value).
5) ADD RECORD -- will add a record to the
currently active file containing the
field values currently displayed.
Deleted record space is used if available;
otherwise, the record is added to the
end of the file.
6) CHANGE RECORD -- will change the current
record to reflect the field values
currently displayed.
7) DELETE RECORD -- will delete the current
record.
