Edit Files in a Fileset

Qedit does not have a built-in command to perform a series of changes on multiple files with a single step. Here is a simple command file that allows this.

Chgset.Cmd:

	parm filesetParm="@"
	purge fileset,temp
	listfile !filesetParm > fileset,6
	purge chgcmds,temp
	:beginfile chgcmds
	:parm filename
	:comment
	:/t !filename,yes
	:comment Insert all your edit commands in here
	:comment be sure to start each line with a colon
	:endfile
	/t fileset
	/d 1/3
	/d "~" (p)
	/c 1 "chgcmds " @
	/u *

The command file creates a temporary command file that will perform the actual edit operations. The version above does not contain any so you have to customize it with the things you want to do. All you have to do is insert the commands between the last :comment line and the :endfile. We recommend that you do not insert a Keep command immediately. Run it a few times without Keep to make sure it makes the appropriate changes. Once you have confirmed that everything works as expected, insert a Keep ,IfDirty to save the changes, if any.

Parameters

The command file accepts one parameter: filesetParm. This is the fileset you want to work on. Its value is passed in to the Listfile command. As such, it can be any MPE fileset, simple or using wildcards. Since the command file uses the Listfile command, the command can work on Posix files if needed. The default is to look for all MPE files in the current group.

Examples

To remove all blank lines from all the MPE files in the current group, the command file needs to be modified like this:

	:beginfile chgcmds
	:parm filename
	:comment
	:/t !filename,yes
	:comment Insert all your edit commands in here
	:comment be sure to start each line with a colon
	:/d "~" (pattern)
	:/k ,ifdirty
	:endfile

To run it, enter:

   chgset

To change all occurrences of the word Display to the word Print in files whose names start with T, the command file needs to be modified like this:

	:beginfile chgcmds
	:parm filename
	:comment
	:/t !filename,yes
	:comment Insert all your edit commands in here
	:comment be sure to start each line with a colon
	:/c "Display" (s) "Print" @
	:/k ,ifdirty
	:endfile

To run it, enter:

   chgset t@

To perform the same changes in all MPE and Posix files, enter:

   chgset ./@
