-
- [ LCK Lisp Checker ]---------------------------------------------
-
- A program written for running checks on AutoLISP files to check
- the balance of parenthesis and double quotes (string literals).
- LCK was introduced as shareware software for use with AutoCAD.
- You may copy and distribute these files freely provided (a) no
- fee is charged and (b) all of the files are distributed together
- in their original, unmodified form. Please use the LCK21.ZIP file
- for uploading to bulletin boards and such.
-
- If you like LCK and find it useful, your $15 registration fee
- would be greatly appreciated. A registration form is provided in
- the file REGISTER.NOW. Registered owners will be notified of
- future releases. Updates of LCK 2.1 will be made available to all
- registered owners for the cost of materials, shipping and
- handling (i.e $5) or the difference in list price.
-
- Please remember that LCK is not "freeware". If you use LCK, you
- must register. The trial period is strictly limited to no more
- than two weeks.
-

- [ Disclaimer ]---------------------------------------------------
-
- There is no warranty for LCK, expressed or implied.
- CAD/Engineering Services and Stan H. Bimson assumes no liability
- for damages, direct or consequential, which may result from use
- of LCK. Use at your own risk!

- LCK Lisp Checker Version 2.1b Manual
-
-
-
- To use LCK from within AutoCAD add the following statement line
- to your ACAD.PGP file:
-
- lck,lck,65536,*LCK (enter filename): ,0
-
-
- [ System Requirements ]------------------------------------------
-
- LCK will only work on a system with a color monitor. Color is
- used as a debugging tool. Programs that allow some color programs
- to run on monochrome monitors will not work with LCK as text is
- written directly to memory address for the color text area
- bypassing DOS or BIOS calls.
-
-
- [ Program Operation ]--------------------------------------------
-
- PARENTHESIS
-
- 15 colors in alternating groups of non-blinking and blinking are
- used to denote or display the level of parenthesis. The opening
- and closing parenthesis have the same color. When the end of a
- code segment is reached unbalanced parenthesis will be noted. If
- parenthesis are balanced the statement CODE OKAY is shown.
-
- COMMENTS
-
- When ever and where ever a semicolon is found, the semicolon and
- the rest of the line is considered a comment. Comments are
- displayed in the color dark cyan.
-
- STRING LITERALS
-
- When a quoted ("") string is found, the quote and all the
- characters that follow until another quote is encountered is
- considered to be a string literal. String literals have to end on
- the line that they start on. String literals are displayed in the
- color light gray. If the program reaches the end of the code line
- and it has not encountered another quote a string error occurs,
- an error message is displayed at the end of the line. When a
- string or quote error has occurred, it can, as it does within
- AutoCAD, unbalance the parenthesis. Correct the quote error and
- rerun LCK to complete the code checking.
-
- NOTE: Text editors that put a carriage return and line feed
- (ASCII 13 and 10) in the text file for the end of line, can fake
- the AutoLISP interpreter. A string CAN continue from one line to
- the next. The double character code is read in as "\n", a single
- carriage return would be read as "\r". This is all in compliance
- with AutoLISP as these control characters are interpreted as
- being within a string. I feel this is not good coding practice
- and LCK does not support strings that continue on two or more
- lines.

-
-
- CODE
-
- Is displayed in the color dark green, all code exceptions have
- been noted. A line of code, with or without comments may be up
- to 255 characters. Long lines are rapped in the display without
- incrementing line numbers.
-
- STATUS LINE
-
- Line count is given on the left side of line 25. Parenthesis are
- counted and the difference of the left minus right is displayed
- on line 25. Quotes are noted as E for even or U for unbalanced.
-
-
- [ Syntax ]-------------------------------------------------------
-
- LCK [d:][path]filename[.ext] [/switches]
-
- The file name extension is ONLY required if the AutoLISP file
- does not have the extension of .LSP.
-
- LCK junk
-
- Or:
-
- LCK
-
- LCK will stop and ask for a file name.
-
-
- /switches
-
- Switches cause a change in LCK's operation.
-
- /S
-
- Scroll screen 23 lines (max) at a time. The screen scroll still
- stops at the end of code segment or the end of the file. Scroll
- count restarts after each end of code segment.
-
- /NC
-
- No comment display, this covers only the comments that start
- within a code line.
-
- /NA
-
- Remove all comments whether they start at the end of a code
- segment or the beginning of a line. Line numbers which are shown
- on the left side of screen are shown correctly. Removed comment
- lines do not change line numbers.
-
- Switches can be combined in the form:
-
- /SNC or /NCS Scroll set to 23 and delete line comments
-

-
-
-
- /SNA or /NAS Scroll set to 23 and delete all comments
-
- /NANC or /NCNA ? Use one or the other, not both, only the first
- condition will be in affect
-
- [ Lisp code requirements ]---------------------------------------
-
- There are several code or file structure requirements for LCK. We
- are not trying to tell or instruct you in how to format your Lisp
- code.
-
- LCK needs to know what is considered a complete code segment. The
- following are the code format requirements that LCK will follow.
-
- For LCK to know the end of a section of code that is to be
- checked:
-
- (A) Place a blank line between the code segments.
-
- ; Is it a string ?
- (DeFun TestForStr(st)
- (= (Type st) 'STR)
- )
-
- ; Is it a List ?
- (DeFun TestForLst(Lst)
- (= (Type Lst) 'LIST)
- )
-
- (B) Place a single semicolon between the code segments.
-
- ; Is it a string ?
- (DeFun TestForStr(st)
- (= (Type st) 'STR)
- )
- ;
- ; Is it a List ?
- (DeFun TestForLst(Lst)
- (= (Type Lst) 'LIST)
- )
-
- Tab Characters
-
- If your text editor inserts a tab character (ASCII 9) instead of
- expanding with space characters be forewarned that LCK will only
- expand the tab to a single space. This may cause the displayed
- code not to look like how you formatted it.

- [ Parting Comments ]---------------------------------------------
-
- I would be pleased to hear any comments on this program be they
- bad or good, I am not a professional programmer but a freelance
- structural steel draftsman that uses AutoCAD. I program heavily
- into AutoLISP and as you see by this program, in Turbo Pascal. I
- feel that this program is a very good aid for any level of
- AutoLISP programmer.
-
- As many people have found out, my business and home telephone is
- one in the same. I wish to thank these people for calling at a
- reasonable hour (at my end). People who have called on Saturday
- and Sunday have occasionally have found me "out". If you call and
- I am "out", please give who ever answers the telephone some idea
- of why you called. My wife and children can not answer questions
- about LCK, Pascal or AutoLISP, but they take good messages and
- generally know when I will be back.
-
- In all these years I have only received one (1) call about a
- "bug" in LCK, I do return calls covering "bug" reports. If you
- experience some problem with LCK please re-read this manual
- before calling, I have had many calls because people do not
- follow the two simple forms of code formatting.
-
- Some people have just called to "shoot the breeze" about a LISP
- program I have written, they have or are writing, AutoLISP in
- general, AutoCAD, Pascal or structural steel detailing. I don't
- really mind these calls, I need a break once and while and have
- even learned more than I have given, but I do have to work.
- Calling on the weekend doesn't help, I don't sit around the house
- or watch TV. It's Boy Scouts, yard work, my family, beta testing
- (someone else's program), programming (my own), or something.
- It's "catch as catch can" most of the time.
-
- I can be reached at two bulletin boards:
-
- The AutoDesk forum on CompuServe, user ID# 73507,3475, I call
- every Saturday morning (once a week) unless I have message
- replies to send.
-
- OR
-
- The EET BBS, Nashville, TN. Telephone (615) 353-3476, which I
- call everyday or every other day.
-
- National AutoCAD Echo or National CAD/M Echo:
-
- If your local BBS carries either of these National Echos, I check
- both as EET carries both.
-
- Mailing Addresses: Telephone:
-
- CAD/Engineering Services (615) 824-4938
- 1038 Forest Harbor Drive
- Hendersonville, TN 37075-9646 USA

- [ Distribution Disk ]--------------------------------------------
-
- Distribution disk and upgrade disk have the files noted in the
- section Supplied Files. These files are found in the root
- directory of the diskette.
-
- The Supplied Files do not take up much disk space. I really hate
- to send out a diskette with all that empty space so there is
- usually a sub-directory named EXTRAS. In this directory are files
- that I find of interest to me, either for DOS operations or my
- dealing with AutoCAD or AutoLISP.
-
- These programs are public domain, some have documentation and
- some don't. I don't support these programs in anyway, nor do I
- take any liability for them, all the risk is incurred by the
- user. These files change from time to time so no documentation
- list is given.
