| Syntax: | MID(string-argument) |
| Discussion: |
The MID function returns a machine ID string and stores it in
the string-argument. The eight-byte string is binary coded with a
unique number based on the Comet serial number. Each byte of the
machine ID string has a value in the range "00" to "FF" hex.
Note: Beginning with Comet 2006.374 this function returns the Comet plug serial number.
Application note: Password validation routines can be developed for user applications using the MID function. The string-argument must be a string variable (single-element or an element of a string array). |
| Example: |
LENGTH 8 & LOCAL VALUE$ . . . MID(VALUE$) . . .This example shows how the MID function is constructed. In the above example, an eight-byte string variable named VALUE$ is defined. In the Procedure Division of the program, the MID function is used to return a unique machine ID. This value is placed in the variable VALUE$. |
