Bell SyntaxBell[arg]Related Functions    Example CallBell[1]DescriptionThe Bell formula function will beep if the specified value is not empty or null.ExampleIf you have a field that is used to mark outdated records (blank if current, filled if outdated) and you want to verify that all records that are outdated have been deleted, you can run a report that checks that field and beeps if it encounters anything in that field. If all records are current, you won't hear any beeps during the report, but if something was left behind, the computer will beep. Concatenate, No Truncate Syntaxcat.c[arg1;arg2;...;argn]Related Functions   cat.tExample Callcat.t[P1F1;1;apply.format["N99999";P1F5]]DescriptionCat.c is used to concatenate two or more character strings without truncating blank spaces. The arguments can be any string contained within quotes (either single (') or double (") quotes), a field/rv/formula containing alphanumeric data, or an integer indicating the number of carriage returns to insert into the text.ExampleIf P1F1 = "Hello" and P1F2 = "There" then cat.c[P1F1;" ";P1F2;" This is a test!"] will return the string "Hello There This is a test!". Concatenate, Truncate Syntaxcat.t[arg1;arg2;...;argn]Related Functions   cat.cExample Callcat.t["This is a test";1;P1F1;rv0]DescriptionCat.t is used to concatenate two or more character strings, truncating blank spaces. The arguments can be any string contained within quotes (either single (') or double (") quotes), a field/rv/formula containing alphanumeric data, or an integer indicating the number of carriage returns to insert into the text.ExampleIf P1F1 = "Hello " and P1F2 = "There " then cat.t[P1F1;" ";P1F2;"This is a test! "] will return the string "HelloThereThis is a test!". Contains Syntaxcontains[arg1;arg2]Related Functions    Example Callcontains[P1F2;"*DataPerfect*"]DescriptionContains searches alphanumeric and text fields for a specified string. Arg1 is the field/rv/string to be searched and arg2 is the string to be searched for. Returns the integer 1 if the search is successful or a 0 if it is not. Strings to be searched for should be enclosed in quotes if a hard-coded string; otherwise search strings may come from report variables or fields. Wild cards (asterisks or question marks) may be used to find strings within text in a field, otherwise the string searched for will have to be the only thing in the field.ExampleIf P1F1 = an alphanumeric or text field and "*sold*" is the search string, then contains[P1F1;"*sold*"] will return a 1 (true) if the string "sold" exists anywhere in P1F1 or 0 (false) if it does not. If the string "sold*" is used, it will be found only if the string exists at the beginning of the field. Convert Text to Number Syntaxconvert[arg1;arg2]Related Functions   apply.formatExample Callconvert["N9999";P1F1]DescriptionConvert is used to change character strings into numbers (G, H, T, D, or N format). Arg1 = the field format that the string is to go to while arg2 = a string value that is to be converted.ExampleIf P1F1 is an alphanumeric field and contains the string "123456" then convert["G$ZZZ,ZZ9.99";P1F1] will return the numeric value 123456.00 (or $123,456.00 when displayed in the field).

Produces the nth (arg3) word bracketed by any of the characters in the mask (arg2).Examplesubfield["Christine C. Babbitt";" ";2] returns a value of "C.". subfield["(602) 123-4567";'- )(';1] returns a value of "602". (Note that the number shown is considered text, not an N, G, or H value.) Substring Syntaxsubstring[arg1;arg2;arg3]Related Functions   apply.formatExample Callsubstring[P1F1;2;14]DescriptionReturns a specified number of characters from a text string starting at a specified location in the string. (Where arg1 = the field, report variable, formula, or text string to pull the new string from; arg2 = the starting location to parse from; and arg3 = the number of characters to cut out of the string.) If you enter a value of 1 or more for arg2, DataPerfect starts counting at the left of the string and counts from left to right. If you enter a value of 0 for arg2, DataPerfect counts characters from right to left.Examplesubstring["Example";3;5] will return "ample" If P1F2 = a numeric field formatted N(999)999-9999 with a value of 8003213249 then substring[apply.format["N(999)999-9999";P1F2];2;3] will return 800 (the area code). substring[" 215 Oak Lane, Hartford, CT";0;2] This formula will return the string "CT" Term Syntaxterm[i;pv;pmt;fv;type]Related Functions   pmt, pv, fv, rateExample Callterm[(.05/12);0;165;-1000;0]DescriptionThis function returns the number of periods (remaining or projected), based upon the data provided [interest rate, present value, payment amount, future value, and type (0=investment/growth or 1=depreciation/loan)].ExampleTo learn how long it will take you to save $1000 of you deposit $165 per month and earn 5% interest (and start with a zero balance), you would enter term[(.05/12);0;165;-1000;0)] (you will have a little over $1000 in 6 months). Today SyntaxtodayRelated Functions   nowExample CalltodayDescriptionToday returns the system date (from the computer's internal clock) in a Julian numeric format (i.e. the number of days since March 1, 1900. When stored in a date field format this number is automatically translated to the appropriate month/day/year. The today function is generally used as arguments in other functions and formulas.ExampleIf the system date is 11 Nov 92 then today will return 33,866, or 1992.11.19 in a date (DYMD9999.99.99) formatted field. Truncate Syntaxtruncate[arg]Related Functions   cat.tExample Calltruncate[P1F1]DescriptionTruncate removes all trailing spaces from a character string.Exampletruncate["Shauna         "] will return "Shauna." A text string can be created by using consecutive truncate functions (i.e. truncate[P1F2] truncate[P1F3]) but it is generally best to use the cat.t function instead. Unary Minus Syntax-Related Functions    Example Call-P1F1DescriptionReturns the negative value of any number.ExampleIf P1F1 = 10 then -P1F1 returns -10. If today = 1992.11.19 then -today returns -33,866. (This is good for sorting records with the most recent date to the top of the list. See "Reverse Date" in the formulas section of this database.) Year Syntaxyear[arg]Related Functions   day, day.of.week, monthExample Callyear[P1F1]DescriptionYear returns the 4 digit year (i.e. 1992) in a numeric format from a date value.ExampleIf P1F1 is a date field with the value 1992.11.19 then year[P1F1] will return the numeric value 1992 which could then be stored in an N9999 field. Some other acceptable formats include the following: year[rv1], year[date[19;11;1992]] and year[today]. Source notes This wiki page was generated from the DataPerfect FORMULA database.
