COMBINE
Name:
Type:
Purpose:
Combine the contents of one or more variables, parameters, or
constants into a single variable.
Description:
Syntax:
LET <y> = COMBINE <x1> ... <xk>
<SUBSET/EXPCEPT/FOR qualification>
where <x1> ... <xk> is a set of one or more response
variables, parameters, or constants;
<y> is a variable that will contain the contents of
<x1> ... <xk> in a single response
variable;
and where the <SUBSET/EXCEPT/FOR qualification> is optional.
Examples:
LET Y = COMBINE Z1 Z2 Z3 Z4 Z5
Note:
The following syntax is allowed:
For example,
LET Y = DATA 1 2 3
LET Y = COMBINE Y Y Y
will contain the values 1, 2, 3, 1, 2, 3, 1, 2, 3.
Note:
The <SUBSET/EXCEPT/FOR qualification> is typically not used
with this command. However, if one is given, it will be applied
individually to all the variables on the right hand side of the equal
sign. It will be ignored for all parameters and constants.
