[esp-r] Re: sed

A very interesting approach indeed. I must try it.

Another solution would be to loop through construction letters and/or 
thicknesses in the  construction database made local.

The drawback would be that to check what has been done a print of the 
shell to a file should be inspected.

The following example is in Perl, but the substance would be almost 
identical in many languages.

Best regards

Gian Luca

!#/usr/bin/perl
my @thicknesses = ( 0.15, 0.20, 0.25 ); # Put here your thicknesses
my $entry = "a"; # Put here the letter of the construction to be changed
my $layer = "a"; # Put here the letter of the layer to be changed
my $your_path_to_config = "./myfolder/cfg/myconfigfile.cfg"; # Put here 
the path to your model configuration file

foreach my $thickness ( @thicknesses )
{
`prj   -file   $your_path_to_config   -mode    text<<YYY
b
e
a
$entry
$layer
n
$thickness
