I have a large free text field that I need to truncate to 50 characters. I have the pre proc worked out as this

set var [lindex $xlateInVals 0]

set xlateOutVals [string range $var 0 49]

It works except the output only includes values in the field up to a space. So if there are spaces in the field it only gets the data up to the first space.

Ideas?

  Ryan,
  
  xlateInVals and xlateOutVals are lists.
  
  So I would use something like lindex to retrieve the needed xlateInVals list item (probably the firs which would have an index of zero).
  
  I would use something like lreplace for xlateOutVals (again probably the first list item).
  
  A space is a list terminator in Tcl and thus since those 2 variables are lists you see the truncation you are getting.
  
  You should ALWAYS treat the variables provided by Xlate (xlateIn… and xlateOut…) as LISTS!!
