The Check Spelling command checks a source member, generic members,
or all members in a file to determine if any spelling errors exist in
the data portion. A typical command would be:
CHKSPELL FILE(xxxx) MBR(yyy)
If errors exist, a spooled file is created with any statements in
error and a column of words that were found as errors.
You must have a dictionary such as the TAADFT dictionary on your
system. The dictionary is accessed by the QTWCHKSP API. Unique
spelling dictionaries can be created with the CRTSPADCT command.
This is part of the Operating System.
Special dictionaries are supplied with the TAA Productivity Tools.
See the discussion with the TAADCT TAA Tool.
The CHKSPELL2 tool is similar to CHKSPELL. The CHKSPELL2 tool
differs in that it checks a string of data for spelling errors.
CHKSPELL checks the records in a source member.
Misleading output
-----------------
Because of the way the API returns errors, the CHKSPELL function will
not always identify the proper statement where the error exists.
For example, you may have spelled the word 'for ' as 'fo '. The
first scan occurs for the word in error followed by a blank. If a
match is not found, a period is added and the scan occurs for 'fo.'.
If a match is not found, a scan occurs for the exact length of the
word in error.
Because of this technique, the spell checking will find the error,
but when it attempts to identify the statement that contains the
error, it may indicate the wrong statement.
If this occurs, position to the statement shown and scan for the word
that is incorrect. You should come to it within a few statements.
Performance
-----------
The performance of the spell check API is not as good as that used by
the Office Editor or Text Management. You should not expect great
performance from CHKSPELL.
The API has significant overhead to begin checking. To improve the
performance of the CHKSPELL command, a block of 2000 bytes is passed
by combining source records. If you have an 80 byte statement area,
up to 25 records are checked each time the spell check API is called.
While spell checking is occurring, the CPU is very busy.
Command parameters *CMD
------------------
SRCFILE The qualified file name of the source file to be
checked. The library value defaults to *LIBL.
*CURLIB may also be specified.
MBR The member to be spell checked. *FIRST is the
default to check the first member in a file. A
single member or a generic member name may be
specified.
CHGDATE If MBR(*ALL) is specified, any date entered will be
checked against the last change date of each member.
If the member was changed on or after the change
date, it will be checked. Members which were last
changed before the change date will be bypassed.
The change date (if any) should be entered in job
format.
The intention of the CHGDATE parameter is to
minimize the performance once an entire source file
is checked. After that point, you may just check
the members that have changed by specifying a change
date.
ESCAPE A *YES/*NO value for whether to send the TAA9893
message as an escape type if spelling errors exist.
*YES is the default.
*NO may be specified to receive a completion
message.
DICT The qualified name of the spelling dictionary to be
used. The default is *DFT which means to use the
DCTARA parameter.
A list of up to 8 dictionaries may be named. A
dictionary must be created by the CRTSPADCT command.
DCTARA An optional parameter that allows a list of
dictionaries to be specified by naming a data area
in library TAADCT that contains the list. The
default is *DFT. A data area may only be named if
DICT(*DFT) is used.
The list of dictionaries must be entered according
to the CRTDCTARA TAA Tool and the data area
containing the dictionaries must exist in the TAADCT
library. Up to 8 dictionaries may be named in the
data area.
If both DICT(*DFT) and DCTARA(*DFT) are specified,
the following rules exist.
1) If the library TAADCT does not exist, the TAADFT
dictionary in TAATOOL is used.
2) If the TAADCT library exists, a data area by the
name of the user of the job is searched for in
TAADCT. If it does not exist, a data area by the
name of SYSTEM is searched for in TAADCT.
3) If neither data area exists the TAADFT dictionary
in TAATOOL is used.
DLTSPLF Determines if the spooled file is deleted if the
correct spelling exists. *YES is the default
meaning to delete the spooled file if no errors
exist. *NO may be specified to retain the spooled
file.
Restrictions
------------
You must have the Dictionary product (DCT) on your system.
In some cases the wrong statement will be identified because of the
way in which the API returns information. See the previous
discussion.
Source created by the Text Management product cannot be spell checked
due to unique values placed in the source.
Prerequisites
-------------
The following TAA Tools must be on your system:
CHKJOBCTL Check job control
FILEFDBCK File feedback
HLRMVMSG HLL Remove message
RTVSYSVAL3 Retrieve system value 3
SNDCOMPMSG Send completion message
SNDESCMSG Send escape message
SNDSTSMSG Send status message
Implementation
--------------
None, the tool is ready to use.
To specify dictionaries other than US in QDCT, see the CRTDCTARA TAA
Tool.
To create unique dictionaries, see the CRTSPADCT command.
