{{DISPLAYTITLE:_TRIM$}}
|
|
The [[_TRIM$]] function removes both leading and trailing space characters from a [[STRING]] value.
|
|
|
|
|
|
{{PageSyntax}}
|
|
:{{Parameter|return$}} = [[_TRIM$]]({{Parameter|text$}})
|
|
|

|
|
{{PageDescription}}
|
|
* Shorthand to using [[LTRIM$]]([[RTRIM$]]("text"))
|
|
* {{Parameter|text$}} is the [[STRING]] value to trim.
|
|
* If {{Parameter|text$}} contains no leading or trailing space characters, it is returned unchanged.
|
|
* Convert fixed length [[STRING]] values by using a different {{parameter|return$}} variable.
