- Clipper [tm] Summer '87 Replacement Disks:
- Fixed Anomalies
-
- Copyright (c) 1988 Nantucket Corp. All Rights Reserved.
- ---------------------------------------------------------------------
-
- We appreciate those users who took time to report porblems and those
- of you who helped us verify them as well. The following anomalies
- have been fixed by the replacement disks sent to all registered users
- of Clipper Summer '87. Those of you who opted for the new
- documentation should also receive the remaining chapters of
- documentation with your replacement disks.
-
-
- APPEND FROM...SDF/DELIMITED with WHILE Clause
-
- APPENDing from a text file, SDF or DELIMITED, and using the WHILE
- option resulted in a doubling of the size of the text file. This
- problem also occurred with the NEXT option.
-
-
- ASORT(get_array)
-
- If you DECLAREd an array, initialized it with NUMERIC data, did some
- GETs into some of them, then performed an ASORT() on the array, it
- would ASORT() the elements that were changed by the GETs independent
- of the other elements.
-
-
- ASORT(semi-filled array)
-
- If you DECLAREd an array, filled about half of it with data, and then
- performed an ASORT(), the unfilled elements assumed the last data and
- the whole array would then be sorted.
-
-
- CLEAR Area Greater than Screen
-
- Now, with the replacement disks, any coordinates beyond the maximum
- boundary will result in non-execution of that command. (This did not
- previously happen.)
-
-
- Clipper + Disk Cache + Expanded Memory
-
- A combination of Clipper, a disk caching utility and expanded memory
- gave an "OPEN error" error upon the opening of index files. (Note:
- It was also reported that the FAT table could be destroyed if this
- error was ignored and you typed "Y" at the "continue?" prompt.)
-
-
- Debug + DOS Shell
-
- Debug's DOS Shell would not be invoked once a USE file had been
- executed. If you insisted, the machine hung.
-
-
- Debug + Display Database + <F3> Indexes Option + NDX.OBJ
-
- Debug's <F3> option of the DISPLAY/DATABASE sub-menu would not show
- the INDEXKEY expressions of open NDX files.
-
-
- Debug + Display/Database + ALT-G
-
- If you "quick-keyed" from Display/Database mode in Debug with the
- ALT-G or ALT-S keys, and CLOSEd all open DBFs before Debug was
- invoked again, you fell into an endless loop.
-
-
- Debug + Display/Database/<F4>Structure
-
- Debug's Display/Database/Structure option would not display the
- structure of a file that had only one field.
-
-
- Debug + Display/Expression
-
- Debug's Display/Expression option returned an "<undefined>" error on
- inquiries that included a function or variable.
-
-
- EMPTY(memo_field)
-
- The EMPTY() function would not operate properly with memo fields.
-
-
- GETting .T. into Logical Memory Variable
-
- Comparisons performed between a .T. logical memory variable and a .T.
- logical DBF field and/or a .T. constant, would not always return a
- true value.
-
-
- Indexing in a Network Environment
-
- In a multi-user environment, simultaneous indexing of different large
- DBFs by different workstations working on the same subdirectory
- resulted in index corruption. This was caused by the temporary file
- CLIPSORT.TMP, created during the indexing of a large DBF, being
- overwritten by each workstation INDEXing.
-
-
- INDEX ON
-
- An INDEX ON finished at the end of file unlike previous Clipper
- versions. REINDEX still returned you to the TOP of the file as
- designed.
-
-
- INPUT TO Memvar + No_entry
-
- Hitting the carriage-return without entering anything at an INPUT TO
- command would returned a "expression error (in macro)" error.
-
-
- INT() + Extra Leading Spaces
-
- The INT() function placed an extra space in front of the number being
- INT()ed.
-
-
- LABEL FORM + Blank Field
-
- 1. The LABEL FORM command, upon encountering a blank field specified
- in the LBL file, would hang on that record.
-
- 2. If in the LBL file, a blank CONTENT field (or a CONTENT field
- that had an expression that evaluated to blank), preceded other
- non-blank CONTENT fields, the system would hang.
-
-
- LOCATE FOR and SET FILTER TO Multiple Macros
-
- If you tried to LOCATE FOR multiple macros that were not
- dot-terminated, the system hung. The same occured with the SET
- FILTER TO command.
-
-
- MEMOEDIT(.F.) + String Greater than Window Length
-
- MEMOEDIT() with the .F. option (browse mode) would not adjust a very
- long string to fit within its window coordinates.
-
-
- MEMOEDIT(one_line)
-
- If you tried to do a one-line MEMOEDIT() window, the auto-scroll was
- thrown off if you typed continuously beyond the end of the window.
-
-
- MEMORY(0) + SET CLIPPER=X
-
- The MEMORY(0) function did not properly adjust with respect to "SET
- CLIPPER=Xnnn.". Now if the "X" value is raised, the MEMORY(0)
- function will reflect the increase by almost the same amount.
-
-
- MEMO_field + CHARACTER_memvar
-
- You could not concatenate a memo field with a character string
- without encountering a "type mismatch" error.
-
-
- NETNAME()
-
- NETNAME() had been completely disabled.
-
-
- Numeric ALIASes
-
- A field could not be referred to by its numeric alias with
- predictable results.
-
-
- PACK
-
- The PACK command could corrupt records if no index files were
- opened.
-
-
- PCOL()
-
- The PCOL() function would not reflect any horizontal changes on the ?
- print statements.
-
-
- PICTURE "@B" + Numeric Punctuations
-
- The "@B" option (left-justified numerics) for the PICTURE clause
- would not conform with punctuated numeric fields.
-
-
- PICTURE "@XC"
-
- The "@XC" option of the PICTURE clause would not display anything for
- a positive number, and both "CR" and "DB" for a negative number.
-
-
- PLINK86-Plus [tm] + LIB Overlay
-
- At link time, when trying to create internal or external overlays, if
- you included "OVERLAY" in the "LIB" directive, you would get a "BAD
- FIXUP COUNT IN SECTION" error. Any attempt to execute the resulting
- EXE hung the machine.
-
-
- Printing Incompatibility with Autumn '86
-
- The SET DEVICE TO PRINT command did not obey "non-print exclusive"
- coordinates as it did with Clipper Autumn '86.
-
-
- RANGE + DBF Field
-
- The RANGE clause returned a "type mismatch..." error if you tried to
- GET into a DBF field. This occured even if the types did match. This
- problem occurred with DBF fields only. GETting into a memvar
- functioned correctly.
-
-
- REPORT FORM + "HEADER" Option
-
- If the HEADER option was used in the REPORT FORM command, the name of
- the report form file was printed in place of the specified header.
-
-
- REPORT FORM + Sub-sub-total
-
- The REPORT FORM command would not Sub-sub-total.
-
-
- RESTSCREEN()ing One Line of Screen
-
- You could not RESTSCREEN() one line of a screen that was previously
- saved by SAVESCREEN().
-
-
- Re-routing Printer Output to File after No-printer Error
-
- If you tried to send output to the printer and the printer was not
- ready, the PRINT_ERROR() function would be invoked which redirects
- the output to a text file. This is what should happen except the
- function would write "garbage" to the file before the data was
- written.
-
-
- SAVE SCREEN TO Memvar to Field
-
- If you saved screens to a DBF, closed it, then re-used it and
- restored from that field, the restored screen would have garbage in
- it or hang the machine.
-
-
- SAVESCREEN()
-
- The SAVESCREEN() function randomly saved more of the screen than
- specified.
-
-
- SCROLL()ing One Line
-
- The SCROLL() function would not operate properly when one line was
- cleared or if there was only one column to be scrolled.
-
-
- SET CLIPPER=S1
-
- The "S1" option of the SET CLIPPER environment setting only cleared
- snow from about three-fourths of the screen. The left side of the
- screen still got snow. Also, if you SET CLIPPER=S1 on a monochrome
- hardware configuration, the machine hung upon execution of a
- Clipper-compiled application.
-
-
- SET FILTER + SET RELATION
-
- A RELATION set in one area would cause an existing FILTER in the
- other related area to lose its expression identifier unless preceded
- with its alias.
-
-
- SET FILTER TO a Logical Field = .T.
-
- If you SET FILTER TO a "logical field = .T.", everything was screened
- out.
-
-
- SET FIXED ON + Picture Clause
-
- You would hang the machine if you did all of the following:
-
- 1) SET DECIMALS to a number greater than the decimal
- configuration in your DBF,
- 2) SET FIXED ON,
- 3) assign a numeric FIELD to a memvar,
- 4) then do a GET on that memvar with a PICTURE clause
- that does not accommodate for the decimals.
-
-
- SORT + (DBF with DBT)
-
- If you SORTed a DBF that had an associated DBT file, the target DBT
- file was truncated to 512 bytes.
-
-
- SUM
-
- 1. The SUM command ignored the DECIMAL configurations of the DBF.
-
- 2. The SUM command randomly returned numeric overflow asterisks
- where it should not have.
-
-
- TYPE()
-
- The TYPE() function was being "indeterminate" in its evaluation of
- functions.
-
-
- VAL()
-
- The VAL() function required that a decimals-only string be preceded
- with a "0" (zero); otherwise, a numeric overflow would be returned.
