A: Yes, see following workaround. This SQR report will actually write another SQR code with column names supplied by the user and execute it. Note that in SQR Version 3.0, dynamic columns are directly supported.

---------------------------- Example code begins here -------------------------
begin-report
	do main
end-report

begin-procedure main
	move 'DEPTNO' to $col1	! You might use INPUT here to prompt the user
	move 'ENAME'  to $col2	! to enter the column and table names instead.
	move 'EMP'    to $tab
	move 'sqrout.sqr' to $sqrpgmnam
	let $syscmd = 'sqr '||$sqrpgmnam||' user/password'
	move 100 to #flatfileid
	open $sqrpgmnam as #flatfileid for-writing record=132
	write #flatfileid from 'BEGIN-REPORT'
	write #flatfileid from '	DO MAIN'
	write #flatfileid from 'END-REPORT'
	write #flatfileid from 'BEGIN-PROCEDURE MAIN'
	write #flatfileid from 'BEGIN-SELECT'
	write #flatfileid from $col1 ' (+1,1)'
	write #flatfileid from $col2 ' (,30)'
	write #flatfileid from 'from ' $tab
	write #flatfileid from 'END-SELECT'
	write #flatfileid from 'END-PROCEDURE MAIN'
	close #flatfileid
	call system using $syscmd #status
	display 'Status of call is ' noline
	display #status
end-procedure
