;EDIT 236
;Remove old SEARCH ALUPRM statement.
;EDIT 235
;Changed version number to 11
;-------
;This version shipped on tools tape with TOPS20 Release 5, although
;edit number had not been updated and was shipped as 233.
;EDIT 234
;Assemble ALUPRM as part of ALU rather than as universal.
;Put back default extension for CANCEL.
;Use ALU: instead of SYS: for second try for help file
;Give extension .RED for REDIT changes file.
;Type REDIT info in neater format

;
;233 6-Jul-81 /DAW If file is RENAME'd to the library, set the
; generation-retention-count to the default of the
; library.
;232 6-Jul-81 /DAW Implement /COPY and /NOCOPY switches on "GET" and
; "QGET" commands.
; FTCGET feature test switch: = 1 means the default
; is /COPY on GET and QGET, = 0 means default is /NOCOPY.
;231 6-Jul-81 /DAW Add "INFORMATION (ABOUT) VERSION" command,
; put out whole version number (including "minor"
; and "who" field) to FILUPD.HST.
; Don't depend on user defining LIB: the same way
; as is in ALU's table for REPLACE to work correctly.
; STATUS to print out "lib: = " before each library
; directory.
; Allow user to be on a different structure and
; REPLACE (until now this hasn't worked with all
; flavors of ALU).
; When replacing generated output files, do the same
; typeout as the EXEC when it does a COPY.
;
;*** VERSION 10 July 3,1981 ***
;
;230 2-Jul-81 /DAW Add another argument to LIB macro; to allow
; different libraries to have different FILUPD.HST's
; and places to put .DIF and .SCM files.
; Changed COMMENT command to ask which library's
; FILUPD.HST you want to put a comment in.
; Also ALUPRM files are now incompatible, so ALU is
; now version 10.
;227 2-Jul-81 /DAW Delete switch FTRCD (use connected directory
; on replaces); this is reasonable for all ALU's
; to do.
; Add DFLIB feature: If you define DFLIB in
; ALUPRM.MAC, it is used as the default library.
;226 1-Jul-81 /DLM RSCAN line handled.
; Get why text from new file if possible.
; CANCEL not fail if copy of file gone.
; Better handling of GTJFN failure on STATUS, etc.
; Allow any user if FTANYU.
; See if file already in connected directory before
; COPY'ing with GET.
; Handle busy on update of FILUPD.HST.
; Replace from connected directory.
; No default directory, code cleanup.
;225 8-Jun-81 /DAW Never set CM%RAI flag - it doesn't work well in
; COMND% JSYS unless you do it all the time. Convert
; the library field by hand to uppercase.
;224 4-JAN-80 /DAW Fix running of FILCOM to look nicer when it happens.
;223 3-DEC-79 /DAW Make DELETE work under TOPS20 V3A.
;222 30-NOV-79 /DAW Put user name in log entry.
;221 21-NOV-79 /DAW Fix problem in edit 220, where ALU no longer knew
; if you were connected to a library. Note: This change
; makes .MAZ files be incompatible (since the structure
; name is now included in them).
;220 20-NOV-79 /DLM Features for the TOPS20 project:
; function switches SWRUID and SWBAKF,
; allow .MAZ files to be in a subdirectory of the library,
; and fix ALU to be able to work across structures.
;217 30-OCT-79 /DAW In log file, say "Replaced LIB:file.ext" instead of
; just file.ext.
;216 21-OCT-79 /DAW ADD and DELETE commands implemented
;215 19-OCT-79 /DAW Created ALUPRM.MAC. Got rid of feature-tested code,
; and made them all run-time switches. Changed name
; of command "INFORMATION (about) FEATURE-TEST-SWITCHES"
; to "INFORMATION (about) FUNCTION-CONTROL-SWITCHES"
;214 18-OCT-79 /DAW Add option to STATUS command to just get the status
; of a particular file.
;213 17-OCT-79 /DAW Add another set of parsing routines for secondary
; command parsing. This improves the usefulness of "?"
; and control-U in certain places.
;212 16-OCT-79 /DAW Do RENAMEs instead of COPYs when built with FTFUID=0.
; Make ALU set date/times of files copied around
; just like EXEC copy. ALU only changes file date/times
; now when built with FTFUID=1.
;211 16-OCT-79 /DAW Improve error recovery when writing the MAZ file.
; Created a subroutine WRTMAZ to modularize the problem.
;
;*** VERSION 7 OCT 16,1979 ***
;
;210 16-OCT-79 /DAW Make several changes to make ALU incompatible
; with old versions. Therefore it is now version 7.
;207 15-OCT-79 /DAW Implement "INFORMATION (ABOUT) EXTENSIONS"
;206 15-OCT-79 /DAW Implement automatic copying of generated output
; files to the library along with the reserved
; file when it is replaced. This feature is controlled
; by switch "SWCOPO".
; Make "INFORMATION (ABOUT) FEA" tell about this.
;205 15-OCT-79 /DAW Implement "INFORMATION" command
; (about: USERS, LIBRARIES, FEATURE-TEST-SWITCHES)
;204 14-OCT-79 /DAW Implement feature test FTFUID - if 0, supresses
; changing the UID line in the updated file
;203 24-AUG-79 /DAW Fix STATUS command to 1) Print Library name
; when 1st reserved file on it found, and "no files
; reserved" otherwise; 2) Print actual file name
; that's reserved instead of "MAZ" name.
;202 23-AUG-79 /DAW Get rid of logical names, move EXTS definition
; up to top of file for easy editing.
;201 23-AUG-79 /DAW CHECK FOR "No such generation number" when
; doing a GTJFN for MAZ file.
;
;** VERSION 6 ** JUL 1, 1979
;
;200 1-JUL-79 /DAW INITIAL VERSION TAKEN FROM KRUPANSKY'S
;
;ABSTRACT:
; ALU is a program to aid developers of TOPS20 software products.
;It provides the following:
;
;1) An interlock mechanism on library files. Only one
; person can be editing a particular file at one time.
;
;2) A record of all changes to the library.
;
; The original version of this program was written in
;SNOBOL in 1978 by Jack Krupansky for the COBOL-79 project.
; It became version 6 in July, 1979 when David Wright rewrote
;it in MACRO for performance and maintainability.
; As more in-house developers started using it, feature-test
;switches were added and the formats of things changed, so in
;October, 1979 it became version 7.
; Dan Murphy (who represented the TOPS-20 monitor group)
;made several enhancements after that, and his source was
;merged in July, 1981 with David Wright's latest source to
;become ALU version 10. ALU was also made to work with REDIT
;in July, 1981 to make its capabilities rival those of STEP.
