Teradata MultiLoad supports concatenation of variables, using the SET command, such as:
.SET C TO 1; .SET D TO 2; .SET X TO &C.&D;
In this example, X evaluates to 12.
If a decimal point is added to the concatenated variables, then X evaluates to 1.2, as in:
.SET C TO 1; .SET D TO 2; .SET X TO &C..&D;
