RE: how to "squeeze" a field of spaces

Joel,

Try this bit of code which uses the %SCAN and %REPLACE built-in functions.

C                   Eval      string      =                            
C                              'String   with    blanks     to  strip' 
                                                                       
C                   DoW       %Scan( '  ': string ) > 0                
C                   If        %Scan( '  ': string ) >                  
C                              %Len( %TrimR( string ) )                
C                   Leave                                              
C                   EndIf                                              
C                   Eval      string      =                            
C                              %Replace( '': string:                   
C                                        %Scan( '  ': string ): 1 )    
C                   EndDo                                              
                                                                       
C     string        Dsply
