-
- ADIR provides a sorted list in a directory format of all Aliases contained
- in the ALIAS.CMD file. ALIAS.CMD must be located in the ROOT directory, the
- last element along your search path. Alternatively, ADIR may be configured
- to search a default directory. If the wheel byte is set, the directory to
- search in the form of DU: or DIR:, may be entered on the command line.
-
- ADIR.COM is for use with an External Environment. If using ZCPR3.3, you
- may use the program as is. For ZCPR3.0, simply patch the address of your
- External Environment at locations 0109h and 010Ah or use Z3INS.
- ADIRIN.COM is for systems which do not support an external environment.

- Syntax: ADIR [dir:][filename.ext] [=mask] [/oo]
-
- Options: N <-- No page pause
- S <-- Display hidden
- P <-- Send output to LST:
- Ln <-- Specify Alias Name length
- Rn <-- Loads alias count into ZCPR register n (1-9)
-
- All tokens are optional. Any invalid or restricted token is ignored.
-
- When ALIAS.CMD, or the selected file, is located in a password-protected
- directory, either by path search or by user selection, the Wheel byte is
- checked and, if not set, the user is requested for the directory password.
- An invalid entry terminates the program.
-
- mask: Takes the form '=mask' and may be up to twenty chars in length. The
- first n chars of each entry are compared to the mask and the entry eliminated
- from the display if no match occurs.

- ADIR Notes - 1/5
-
- a. ADIR assumes that the ALIAS.CMD file adheres to a few simple rules:
-
- 1. ADIR ignores any line beginning with a space or semi-colon. Aliases
- beginning with a punctuation character are special cases. The
- leading character is normally ignored and the alias is displayed as
- though it did not exist.
-
- Thus the line:
- :default Z3ERROR
- is ignored, while
- :DEFAULT Z3ERROR
- would be displayed as:
- DEFAULT
-
- If the /S switch were used in the above example, then both aliases
- would be displayed as found, including the leading colons.
- ADIR Notes - 2/5
-
- 2. ADIR assumes that any alias beginning with a lower case letter (a-z)
- is "system" or hidden. These are not displayed nor included in the
- final tally (see switch /S). Thus the lines:
-
- PACK ROOT:;PUBLIC /CA;PACK2;PUBLIC /DAU8;%D0%U0:
- pACK2 LX SAP;LX PACK10
-
- produce only one entry, "PACK" in the directory. The rest of the
- alias name may be in either upper or lower case, although, if the
- CAPSON flag is left off and hidden aliases appear in ALIAS.CMD in
- lower case characters, they become easily distinguishable in the
- directory when the /S switch is used. Hidden aliases may also occur
- in either upper or lower case, or in numeric or other form following
- a special comment line which takes the form: ;PRIVATE. The word
- PRIVATE must occur in upper case. No entries following this line
- are displayed unless the /S switch is present on the command line.
- ADIR Notes - 3/5
-
- 3. "Equated" aliases are treated as separate entries.
-
- ie. SD=?DIR=D=dIR/? produces two entries: SD and D, while
- ?DIR and dIR/? are ignored as explained above.
-
- 4. Finally, ADIR assumes by default that the maximum length of an alias
- name will be nine characters. This may be altered by changing the
- value of ALENTH as explained above. Any alias name which exceeds
- the value of ALENTH is truncated and appended with a semi-colon to
- indicate that it has been truncated.
- ADIR Notes - 4/5
-
- b. Version 2.3 updates:
- - removes code which prevented any alias beginning with a punctuation
- character being displayed in the non-hidden format. This code also had
- the side effect of hiding aliases beginning with numeric characters.
- - recognizes any character with the exception of ":" and "_" in the
- first character position.
- - bug is also fixed which caused ADIR to hang up if the ALIAS.CMD file
- happened to end with a blank line, CR or LF as the last character in the
- file.
-
- c. Version 2.4 updates:
- - corrects a recursion problem in version 2.3 if any of the options were
- used in previous runs. All flags are not reset each time the program
- is re-entered.
- ADIR Notes - 5/5
-
- d. Version 2.5 updates:
- - adds 'truncation' of alias names which are longer than ALENTH. Long
- aliases are presented terminated with a semi-colon. The truncation
- character is patchable at the label TRNCHR.
- - adds test for commented lines (beginning in ";").
- - adds /Ln switch for length specification from the command line.
-
- e. Version 2.6 updates:
- - terminal data now taken from TCAP if available. If no TCAP is
- installed, the values at TLINE and PLINE are used.
- - in addition to 'lower case' hidden aliases, any alias present after the
- comment line ';PRIVATE' is treated as hidden
- - alias count may be directed to one of the ZCPR registers (1-9)
- - accepts search mask from command line
- - optional default DU to find ALIAS.CMD if non-wheel
- - accepts filename from command line regardless of wheel state
- - internal environment no longer supported

-
- NOTE 3
- Set ALENTH to the maximum number of characters in an alias name. If any
- alias exceeds this length, you'll have trouble. The number of aliases printed
- on a line is a function of ALENTH and TLINE. With the default settings the
- display is eight columns wide. The formula for the number of columns is the
- integer of TLINE divided by ALENTH. Thus if you want a display of six columns
- on an eighty character terminal, set TLINE to 50H and ALENTH to 0DH. The
- display would then be left justified with 13 chars allotted to each entry.
-
- As a footnote, it should be remembered that the larger ALENTH is, the fewer
- actual records ADIR will be able to handle. This will not be a problem in
- most cases as ADIR uses all of available memory for the data table up to the
- location of the CCP. This means that with the default setting ALENTH=10, over
- 4400 Aliases could be accomodated.
-
- NOTE 4
- This is the truncation character. The semi-colon was chosen as it is the
- single character which is least likely to appear in a command name, being the
- command separator character on most systems.

-
- NOTE 5
- DEFDU provides an alternate method of determining the default directory for
- non-wheel users. If the first byte is set to FF hex, then the normal ROOT
- search method isused. Otherwise, and as the default, the default DU may be
- specified. Byte 1 represents the drive, where A=1; and byte 2 the user area,
- 0-31. The ROOT search method is always used if the wheel byte is set and may
- be overridden from the command line.

- Error Messages
-
- "du:ALIAS.CMD not found."
-
- - ADIR was unable to locate the file ALIAS.CMD in either the root directory
- by default, or in the specified directory by user selection.
-
- "File too large. ABORTING"
-
- - ALIAS.CMD contains more alias names than can be accommodated in the
- available TPA.
-
- "Can't Sort. File too large"
-
- - ADIR ran out of buffer space while attempting to sort the list.
