COBOL/400 Language Help
EXTDSPOPT specifies the options to use for extended ACCEPT and extended
DISPLAY statements for workstation I/O, and takes the form:
EXTDSPOPT(a b c)
Where a is DFRWRT or NODFRWRT, b is UNDSPCHR or
NOUNDSPCHR, and c is ACCUPDALL or ACCUPDNE.
- DFRWRT indicates that extended DISPLAY statements are held in a buffer
until an extended ACCEPT statement is encountered, or until the buffer is
filled. DFRWRT is the default value.
If an extended ACCEPT statement is not encountered before the buffer is
filled, the contents of the buffer are written to the display. When an
extended ACCEPT statement is encountered, the current contents of the buffer
are written to the display.
- NODFRWRT indicates that each extended DISPLAY statement is performed as it
is encountered.
- UNDSPCHR indicates that displayable and undisplayable characters are
handled by extended ACCEPT and extended DISPLAY statements. UNDSPCHR is
the default value.
- NOUNDSPCHR indicates that only displayable characters are handled by
extended ACCEPT and extended DISPLAY statements.
Although you must use this option for display stations attached to remote
3174 and 3274 controllers, you can also use it for local work stations.
If you do use this option, your data must contain displayable
characters. If the data contains values less than hexadecimal 20, the
results are unpredictable, and can range from unexpected display formats to
severe errors.
- ACCUPDALL indicates that all types of data are predisplayed in the
extended ACCEPT statements regardless of the existence of the UPDATE
phrase. ACCUPDALL is the default value.
- ACCUPDNE indicates that only numeric edited data are predisplayed in the
extended ACCEPT statements that do not contain the UPDATE phrase.
To specify if you want flagging of COBOL/400 functions that are not
supported by SAA COBOL:
- NOSAAFLAG indicates that SAA COBOL flagging is not performed.
NOSAAFLAG is the default value.
- SAAFLAG indicates that SAA COBOL flagging is performed.
FLAG(nn) specifies the minimum severity level of messages to be
printed.
- 0 indicates that all messages are printed. This is the
default value.
- severity-level (a one or two-digit number) indicates the
minimum severity level of messages that are printed. Messages that have
severity levels of the specified value or higher are listed.
For file status 9M:
- NOFS9MTO0M indicates that file status 9M is not changed to file status
0M. This is the default value.
- FS9MTO0M indicates that file status 9M is changed to file status
0M.
The GRAPHIC option of the PROCESS statement is available for processing
DBCS characters in DBCS literals. This option is for DBCS systems
only.
- NOGRAPHIC indicates that DBCS characters in DBCS/SBCS (mixed) literals are
processed. This is the default value.
- GRAPHIC indicates that DBCS characters in DBCS literals are
processed.
For file status 9A:
- NOFS9ATO0A indicates that file status 9A is not changed to file status
0A. This is the default value.
- FS9ATO0A indicates that file status 9A is changed to file status
0A.
