Re: Formatting Data in RPG 4

Okay, change all the input_record with %TrimR(input_Record).
Or make a new var, input_trimmed and give it the trimmed right value of 
input_record.
You'll need to use a varying length field to store the trimmed value though.

Pseudo code:

Output_record = blanks
do until end of file
  read input_record 
  if length(output_record) + length(%TrimR(input_record)) > 80
      length_to_add = 80 - length(output_record)
      output_record = output_record + left(input_record, 1, length_to_add)
      write output_record
      output_record = right(%TrimR(input_record), length(%TrimR(input_record)) 
- Length_to_add)
  else  
      output record = output record + %TrimR(input_record)
  end if
end do
if length(output_record) > 0
  write output_record
end if

Or, optionally:

Pseudo code:

D InputTrimmed    Varying

Output_record = blanks
do until end of file
  read input_record 
  InputTrimmed = %TrimR(Input_Record)
  if length(output_record) + length(input_trimmed) > 80
      length_to_add = 80 - length(output_record)
      output_record = output_record + left(input_trimmed, 1, length_to_add)
      write output_record
      output_record = right(input_trimmed, length(input_trimmed) - 
Length_to_add)
  else  
      output record = output record + input_trimmed
  end if
end do
if length(output_record) > 0
  write output_record
end if
