Description
Identifies the source code that follows as a subroutine. Use in the first line of code.
Note: The maximum length of a stored procedure executable is 64 Kilobytes. This limit applies only to the compiled object. The subroutine source code may exceed the 64 Kilobyte limit.
Syntax
Begin Condition Pre: Post: End Condition [Compile] Subroutine name(DataType parameter [DataType parameter, ...])
Parameters
The Subroutine statement has the following parameters.
| Parameter | Description |
|---|---|
| name | Any legal variable identifier can be used as the name of the subroutine. |
| DataType | OpenInsight does not require data typing of subroutine parameters. Specify the data type before the parameter identifier. Mat is available as a data type. |
| parameter | A parameter is optional, and can contain a variable, matrix, constant, or expression. If used, the parameter specification must be enclosed in parentheses. If no parameter is specified, the parentheses are omitted. Multiple parameters are delimited with commas. Parameters are formal definitions for arguments (actual values) to be passed to and from the calling procedure and the subroutine. The calling procedure must provide the same number of arguments as parameters specified in the called function. If fewer arguments are provided, those not provided will be unassigned. If more are provided, an error will occur. |
