Cool. It's working as intended then. Thanks for the feedback...

Hi Steve
thanks a lot 
this works: TEXT ('[area]' + ' acres')


An Overview of what I tried und the results

TEXT ([DB_FIELD]+'L')
	yyparse(): Expression parser error. syntax error
	msShapeGetAnnotation: Expression parser error. Failed to process text expression: [DB_FIELD]+'L'

TEXT ([DB_FIELD],'L')
	yyparse(): Expression parser error. syntax error
	msShapeGetAnnotation: Expression parser error. Failed to process text expression: [DB_FIELD],'L'

TEXT ('[DB_FIELD] L') 
	=> shows Label exact as between '' e.g. [DB_FIELD] L
	
TEXT ('[DB_FIELD]'+' L')
	=> ok
 
TEXT '[DB_FIELD] L'
	=> ok
	
TEXT 'L [DB_FIELD]'
	=> ok

TEXT '[DB_FIELD]'
	=> ok

TEXT [DB_FIELD]
	=>in PHP-Script catched Exception 
	'MapScriptException' with message 'Failed to open map file "a.map"'
	=>in MS_ERRORFILE
	getSymbol(): Symbol definition error. Parsing error near (DB_FIELD):(line 739)

Best regards,
Ralf
