Appendix C Formula Functions Reference 489
Row State Functions
• Week Of Year(2752272000) returns the number 12.
• Time Of Day(2752272000) returns the number 0.
Informat
The argument for the Informat function is a date character string. For example, Informat("03/20/1991")
returns the appropriate JMP date value, 2752272000. JMP can read all the date formats except for
Abbrev Date and Long Date.
Abbrev Date, Long Date, Short Date
The argument for these date functions is a JMP date. They return character strings that are the
formatted representation of the argument. For example:
• Abbrev Date(2752272000) returns Wed, Mar 20,1991.
• Long Date(2752272000) returns Wednesday, March 20, 1991.
• Short Date(2752272000) returns 3/20/91.
Format
The first argument in the Format function is a JMP date. This function returns the character string
representation of the date by the date format you specify in the second argument, which is a quoted
string. If you apply this formula to a numeric column, JMP automatically changes the column’s data
type to character.
You can also supply a column for the first argument and leave the rest blank. The result is the formatted
value of the column reference. This can be used to extract value labels of a column when the value
labels are turned off.

MDYHMS
The argument of MDYHMS is a JMP date. This function shows all date and time fields, appending
zeros as time fields if no time information is present. This is useful if a date column is formulated such
that not all date information is displayed. The MDYHMS function can be used to see all available date
and time information.
Row State Functions
There are six characteristics that rows in a data table can have: selected, hidden, excluded, labeled,
colored, and marked. If you give rows one or more of these characteristics and then create row state data
table columns, you can then create a formula that computes and saves row state conditions. (See
“Assigning Characteristics to Rows and Columns,” p. 131, and “Using Row State Columns,” p. 165, for
more details.)This formula processes row state data just as it would process character and numeric data.
See the JMP Scripting Guide for details about syntax.
Row State
Returns the active row state condition of the current row as true or false. You can use this function to
conveniently write conditional clauses that depend on the status of the current row. For example,
Figure C.19 assigns a 1 to rows that are currently selected and labeled and 0 otherwise.
