Greetings.

i have to do some sort of string manupulation. Please refer the code below.

3 WST-EBH-AMEX-AREA GROUP 52 38 47 10
4 WST-EBH-AMEX-FORMAT-CODE
XX 53 38 39 2
4 WST-EBH-AMEX-INV-NBR XXX 54 40 42 3
4 WST-EBH-AMEX-SUB-CODE XX 55 43 44 2
4 WST-EBH-AMEX-CURRENCY-CODE
XXX 56 45 47 3

i read the above piece of code into one array and moved the data of 3rd line and 6th line(split line) into 2nd and 5 the line (original line) respectively. after i moved the datas i wanted to delete the split lines.

i tried to delete the same using DELSTR() function. but no fruitful results.

Regards

The easiest way is to use two arrays (stem)
Code:
'execio * diskr myinput (finis stem inp.' /* for example */
out. = ''
ixO = 0
do ixI = 1 to inp.0
   if <new line> then do
      ixO = ixO + 1
      out.ixO = inp.ixI             /* start new line */
   end; else do
      out.ixO = out.ixO inp.ixI     /* append line to previous */
   end
end
/* out. now contains reunited lines */
