TeleFlow Variables

TeleFlow Variables are loosely defined and are processed according to their context. The format definition of the variable will determine what type of information the variable represents. For example, a TeleFlow Date is determined when it is stored as "YYYY/MM/DD". A TeleFlow Time is stored as "HH:MM:SS". Numeric and string values are treated accordingly.

Variable Naming Rules

• A variable is denoted with an @ symbol
• A variable name must start with a letter or an underscore "_"
• Only letters (a...z, A...Z), numbers (0...9) and underscores ( _ ) can be used in variable names.
• A variable name may not contain spaces. If a variable name is more than one word, it must be separated with underscore (@my_string), or with capitalization (@myString)
• For variable names, TeleFlow is not case sensitive. It treats all variables as being in UPPER CASE, regardless of how they are referred to in the application.

System Variables

There are TeleFlow System Variables which provide information about the operating environment, and there are user defined variables

Formatting Variables

TeleFlow's variables can be placed together in strings in order to define a new value. The following constructs will help you build strings when other characters are included. This example includes multiple variables to create a unique file name:

@dictationFile=Dictations\\dictation_U@{pU_ID}_C@{pCommand}_T@UNIX_TIME.wav

The value created and stored in @dictationFile might look like:

Dictations\\dictation_U2_C19_T1213228616.048.wav

Accordingly:

• The curly braces { } are used to isolate variable names from other characters:
  • @pU_ID (does not include the following underscore and C)
  • @pCommand (does not include the following underscore and T)
• @UNIX_TIME, a system variable, is delimited with a period (.), which cannot be included in the variable name.
• In this case, the double backslashes are required for MySQL
