Fixed base
The base value of the range.
- 1-7 characters, in this format:
- First character: alphabetical (A - Z) or national characters @, #, or $
- Characters 2 - 7: alphanumeric or national characters @, #, or $
- You can also enter a system symbolic (begin with an ampersand, include
at least one character and end with a period, as in LU&MVS1.).
The length of the base value plus the length of the lower range cannot exceed 8 characters.
