NDL++ functions can be used in the map specification and the NULLIF, MISSINGIF, and SKIPIF clauses of ndlm import specification script files. They are typically included in the map specification (table-name section) to specify operations to be performed on input data. Analytical functions are useful for inclusion in variables and conditional expressions.
Note:
The examples presented in the following sections use the UNIX end-of-record character (\n), as opposed to the Windows characters (\r\n). In practice, use whichever end-of-record indicator is appropriate to the data file referenced by the specification script.
