(inverse of NORMSDST)
NORMSD/D12.5 = NORMSDST ( Z, D8); NORMSI/D12.5 = NORMSINV
(NORMSD,D8); SIZE/D12 = NORMSI * STDEV + MEAN; Equivalent to the

- IF criteria can now reference RDBMS variable character data
types
-
- VARCHAR, LONG VARCHAR, and CLOB now up to 32K
-
- Described in the Master with USAGE=TX, ACTUAL=TX
- Read-only selection performed by RDBMS improves
performance
- Must use CONTAINS or OMITS against a TX field
- In the SQL, CONTAINS becomes LIKE, and OMITS becomes NOT
LIKE

SET USERFCHK
- Verifyand fixarguments of FOCUS functions or DEFINE
functions
- Adjust the level of error checking of parameter lengths and
type specifications
- SET USERFCHK =ON/ FULL / OFF / ALERT
-
- ON (default) Attempts to fix a length problem.
-
- If fixed, displays a warning; if not, displays an error
-
- FULL Same as ON but also checks functions in MFD
-
- OFF Turns verification off except in extreme cases
-
- ALERT Same as OFF but a warning message is issued

phrase causes the first line of the FML hierarchy to indent seven
spaces (five + two). 33. Indenting FML Hierarchy SET
BLANKINDENT
- Specify the indentation between FML hierarchy levels
- Valid in HTML, PDF and Postscript reports
- Indents captions 0.125 or n units per normal space

characters (including dots)Specify via Wide-Lines focexecs or amper
variable substitution 64-character segment names only in XFOC
files. Segment names in FOC files remain up to 8 chars. *
- Compound length limit raised to accommodate the longest name
for all components
57. More ACROSS Values
- Number of displayable ACROSS field values increased from 95 to
1,056

58. 1,024 Display Fields
- Number if fields in a single or pooled TABLE request increased
from 495 to approximately 1,024
- Actual maximum for a specific report is influenced by:
-
- Temporary fields (COMPUTE and DEFINE)
-
- Internal fields, like TABPAGENO
-
- Field references in headings and footings
Great for extracts to Data Warehouse!What else? 59. More Sort
Headings and Footings
- Now up to 32K reserved for sort headings and footings
- Up to 64 total SUBHEADs and SUBFOOTs
-
- Great power combined with WHEN
- Independent of area reserved for HEADING and FOOTING

- Automatically adjusts to memory available
61. More External Index Partitions
- External Index partitions increased from 120 to 240 max
- Dependent on File Control Table* spares during session
- (External Index file up to 2gig)

Operating System FOCUS 7.3 63. Get User Name from Amper Variable
&FOCUSER
- System amper (&) variable retrieves the logon ID
- Use instead of the GETUSER function
- Supported anywhere an amper variable can be used
- Ok in MODIFY, but not inCompiledMODIFY.Why not??
-
- IF EDIT(&FOCUSER,$$$$9999) . . .
Examples: 64. Wide Lines for Focexecs, Masters, Access Files
- Lrecl >80 for focexecs, masters, access files
- Entire TABLE or SQL statement on one line
- Some commandsrequireseparate lines
-
- MODIFY syntax, END, HEADING and its text
65. Wide Lines for Focexecs, Masters, Access Files Examples
DEFINE FILE CAR FIELD/A4096 = ABC D E F G H I J T U V W XYZ ; TABLE

Call Your System Editor for Wide-line Files IEDIT
- Work with files of lrecl > 80
-
- Needed for Wide Lines which TED does not support
- Call to your system editor (XEDIT or ISPF)
-
- Your editor profiles and macros remain in force
- Several TED-like conveniences
-
- IEDIT with no argument recalls last-run focexec
-
- File displays at line number of last error
-
- RUN command saves and executes the focexec
67. Relative GDG + 1
- Relative GDG (Generation DataSet) may be a positive number as
well as negative number
- Plus creates a new generation entry in the catalog to be
generated later with HOLD or SAVE

MAINTAIN MAINTAINEnhancements FOCUS 7.3 69. MAINTAIN Filetype
Extension
- MAINTAIN procedures can have a file extension of MAINTAIN
instead of FOCEXEC (for both MVS and CMS)
- MNTCON is required to work with MAINTAIN procedures that have
their own extensions
MNTCON EX maintproc MNTCON COMPILE maintproc MNTCON RUN
maintproc //MAINTAIN DD=myqual.MAINTAIN.DATA,DISP=SHR maintproc
MAINTAIN A1 MVS JCL VM will look for the new extension still
FOCCOMP 70. New Screening Conditions for MAINTAIN
- NOT_INtrue when a field is not in a list of values
- e.g. For All Next CountryWhere Country NOT_IN
("ENGLAND","FRANCE");
- EQ_MASK and NE_MASK Compares a database fieldto a computed
field using wildcard character ($)
-
- Example:Compute afld/a8="$$$LAND"; For All Next Country Where
Country EQ_MASK afld ;
FOR ALL NEXT fields [INTO stackname] WHERE fieldNOT_IN list
(item1, item2 [,] ) EQ_MASK mask NE_MASK mask CONTAINSstring OMITS
string MASK may contain $ wildcardsEx : ABC$E$$G looks
foranycharacter in those positions 71. FOCUS SETs from MAINTAIN
-
- Use SYS_MGR.FOCSET function to pass aSET option and its
value
-
- Example:SYS_MGR.FOCSET("CDN","ON");
