I want to replace on DCL level some string patterns in a file ,how can I do it? In unix from example there is a command utily SED which can be used to replace strings in a file.

SED is available for VMS as well. Best is to get the freeware GNV package. Follow the freeware path at the VMS home page to http://h71000.www7.hp.com/opensourc... Also PERL is availabe for VMS, follow the above opensource or freeware links at HP. There a zillions of find-replace scripts on the the various perl archives. You can as well use VMS editors like TPU/EVE, see examples in my utilities directory: http://wwwvms.mppmu.mpg.de/~huber/u... And interactive, using the EDT editor: edit/edt/comm=sys$input tmp.tmp s/old/new/wh exit changes all strings "old" to "new" in file tmp.tmp.

In addition, without installing anything else to basic VMS, see my GSR.COm (Global Search and Replace): http://wwwvms.mppmu.mpg.de/util_roo...
