SQL code to find the longest line

I have a SQLPRGLE program compiled to a target release of V5R4M0
that works correctly in V7R1M0, but throws a SQL exception when
processing the prepare statement. The purpose of the
code is to simply find the longest line in the file.

/ Eval cmdSQL = 'DROP ALIAS QTEMP/AA';
/ exec sql Execute Immediate :cmdSQL;
/
/ Eval cmdSQL = 'CREATE ALIAS QTEMP/AA FOR QTEMP/DISP(DISP)';
/ exec sql Execute Immediate :cmdSQL;
/
/ cmdSQL = 'SELECT MAX( LENGTH( TRIM(DISP) ) ) FROM QTEMP/AA';
/ exec sql prepare s1 from :cmdSQL;

SQL values after processing the prepare statement:

sqlcod = 204
sqlerm =
....5...10...15...20...25...30...35...40...45...50...55...60
' *ALL *N MEM '
' '

Does anyone know if there is an issue with the above code?
