You can place symbolic variables in any combination in SYSIN01 control statements to create composite parameter values. You can use a period (.) as a terminating character for the symbolic variable, but this is not required. If a period is present, it is removed from the resultant field content.
Example
ID=X-&TIME(HH):&TIME(MM):&TIME(SS)
This results in the value for ID being set to:
X-15:31:28
If the symbolic variable does not have a system value, you must assign a value before using the symbolic variable. You can also specify subscripts on symbolic variables that do not have a format-code. There are two formats for subscripted symbolic variables. If only one numeric value is present, a starting position of 1 is assumed. A second subscript format allows for a starting position as well as a length to be entered:
Example (one subscript)
LU=L784000 ID=LU#&LU(4)
This results in the value for ID being set to:
LU#L784
Example (two subscripts)
LU=LU250021 ID=LU#&LU(5,4)
This results in the value for ID being set to:
LU#0021
