Concept

Purpose

The 58 DataEase functions execute calculations, manipulate text, and perform other time-saving data-entry operations. There are nine groups of functions, briefly summarized below.

  • The if function returns one of two values based on its evaluation of a specified condition as true or false.

  • Date functions convert a date into a number representing the day, month, year, day of the week, or day of the year on which the specified date falls.

  • Spell functions convert a date or numerical value into its equivalent text value.

  • Time functions extract the hour, minutes, or seconds from a 24-hour format time value or assign the appropriate AM or PM suffix.

  • Text functions are used to concatenate, truncate, or manipulate a text value.

  • Financial functions calculate either the beginning value, end value, interest rate, installment amount, or number of payment periods for a financial transaction, given the values of the other four variables.

  • Scientific functions raise a base value to a power, derive natural and base 10 logs, or derive the square root of a value.

  • Trigonometric functions convert a numeric value into a value expressed in radians.

  • Math functions perform common mathematical rounding operations or return the absolute value of a specified numeric value. The random function generates a pseudo random number.

 

For a full explanation of any DQL function, see the entry listed under the function's name in this Language Reference.

Interface functions and forms

Re:Problem with GetGlobal / SetGlobal functions while checking procedure .

Hmmm… This is a little headache. SetGlobal(), GetGlobal() is an internal function now not a CDF. And it is defined with “names” rather than numbers to make it more useful. SetGlobal(“MyVar”,MyValue) GetGloba...

Re:Re:Problem with GetGlobal / SetGlobal functions while checking procedure .

It's not a good idea to change how existing functions, etc, work, especially with such a commonly used function as this one.Could you not have given the internal version of this function a different name? e.g. GetVariable, or GetVar.Ther...

Re:Re:Re:Problem with GetGlobal / SetGlobal functions while checking procedure .
