Trim
The Trim function returns a copy of a string with no leading or trailing spaces.
Syntax
variable = Trim ( TrimString )
Example
The following example program shows the use of the trim functions to remove the leading and/or trailing spaces from a string.
The InputString is intialized as a text string with 5 leading spaces and 5 trailing spaces. However, the InputString can be changed, so you can see the effect of different string entries when processed by the functions. Results can be viewed easily by collecting the data and viewing the file.
Public TrimRight as String * 50, TrimLeft as String * 50, TrimAll as String * 50
Public InputString AS String * 50
DataTable (TrimTab,True,-1)
Sample (1,TrimLeft,String)
Sample (1,TrimRight,String)
Sample (1,TrimAll,String)
EndTable
BeginProg
InputString= " This is a test "
Scan (1,Sec,3,0)
TrimLeft = LTrim(InputString)
TrimRight = RTrim (InputString)
TrimAll = Trim (InputString)
CallTable (TrimTab)
NextScan
EndProg
Remarks
The TrimString parameter is the string that should be stripped of leading and trailing spaces.
To trim leading spaces only, use LTrim. To trim trailing spaces only, use RTrim.
