vector (dataloop)#


Specifies the creation of a new variable within a data loop.


vector # numvar = numeric_expression()#
vector # numvar = character_expression()#


vector const = 1;


A numeric_expression is any valid expression returning a numeric value. A character_expression is any valid expression returning a character value. If neither ‘$’ nor ‘#’ is specified, ‘#’ is assumed.

vector is used in place of make when the expression returns a scalar rather than a vector. vector forces the result of such an expression to a vector of the correct length. vector could actually be used anywhere that make is used, but would generate slower code for expressions that already return vectors.

Any variables referenced must already exist, either as elements of the source dataset, as extern’s, or as the result of a previous make, vector, or code statement.
