● Access a list variable—Use the following syntax:
let
str_var
|
num_var
=
%listname
[
num_var
|
num_lit
].
#colname
● Modify a list variable—When you modify a list variable, you can modify a specific row
element of any list item.
In list-variable arguments, the value between the brackets indicates either the number of rows
in the list for the definition case or the row within the list to be modified or assigned.
If no brackets exist, there is no need to predefine; assign the types based on the given variable
types. For multirow lists, the assignment must be compatible with the types given in the
definition.
A
NUMBER field has the same characteristics as an undeclared
#var
; the underlying storage
depends on the contents, and the
DEFAULT-NUMERIC setting applies.
The usual SQR Production Reporting rules for variable assignment apply to list access.
Assignment is prohibited only between Date and Numeric types. Assignment of a numeric
column to a string variable returns the string representation of the numeric value; assignment
of a date variable to a string variable returns the default-edit-mask representation of the date.
SQR Production Reporting Reserved Variables
When you create multiple reports, the variables apply to the current report. SQR Production
Reporting reserves a library of predefined variables for general use.
Note:
All of SQR Production Reporting's reserved variables are global variables. Reference reserved
variables in local procedures with a leading underscore. For example, #_sqlstatus or $_sql-
error. See “BEGIN-PROCEDURE” on page 67 for information on defining local procedures.

Variable
Description
#current-column Current column on the page.
$current-date Current date-time on the local machine when SQR Production Reporting starts running
the program.
#current-line
Current line on the page. This value is the physical line on the page, not the line in
the report body.
Line numbers are referenced in PRINT and other SQR Production Reporting commands
used for positioning data on the page. Optional page headers and footers, defined
