EC Gateway provides these generic variable names for programming processes: Parameter – x, FileName – x, Count – x, Message – x, and Resource –x. The character x represents a number that further differentiates the variable. A range of numbers is available for each variable:
Parameter 1– 20, example: Parameter-19. Parameter variables hold alphanumeric fields. Use Parameters to hold alphanumeric data such as file name hold area, text hold area, etc.
FileName 1 – 10, example: FileName-6. Filename variables hold alphanumeric fields. Use Filename variables to hold path and file name structures.
Count 1 – 10, example: Count-8. Count variables hold numeric fields. Use Count variables to store and manipulate numeric data. Use Count variables for loop counters, file size, and Run IDs.
Resource 1– 10, example: Resource-3. Use Resource variables as system global variables. You can use Resource variables to control whether a process runs concurrently with other processes or exclusively within EC Gateway. Examples of exclusive processes are system backups, archiving of a directory, locking of a modem just before it is to be used, etc.
Message 1 – 10, for example: Message-3. Messages usually contain buffer addresses for data of any datatype.
Keep careful track of these variables when you are developing a process. In addition, remember that a limited number of variables (50) can be in use at any one time. However, you can reassign and reuse variables at different points within the process.
