ERROR: demoroutine.int(1) #1026: Invalid command : 'write

Hi,

I am getting following error while compiling a routine :

Compilation started on 08/05/2021 12:58:31 with qualifiers 'cku /checkuptodate=expandedonly'
Compiling routine : demoroutine.mac
ERROR: demoroutine.int(1) #1026: Invalid command : 'write "Use one of the following options"' : Offset:6 [write^demoroutine]
 TEXT: write "Use one of the following options"
Detected 1 errors during compilation in 0.022s.

Please note that Routine contains just a below simple write command :
write "Use one of the following options"

Thanks
