but when i execute this it gives me the following run-time error
Only flat, character-type data objects are supported at the argument
position "LISTASCI" for the statement
"DESCRIBE".
In this case, the operand "LISTASCI" has the non-character-type or deep type
"ZSTRU1_ZMM45". The current program is flagged as a Unicode program. In the
Unicode
context, type X fields are seen as non-character-type, as are
structures that contain non-character-type components.
pls sugges me what should i do.
Thanx
