For 2021 - online Python 3 training - see ((here)).

Our plans were to retire in summer 2020 and see the world, but Coronavirus has lead us into a lot of lockdown programming in Python 3 and PHP 7.
We can now offer tailored online training - small groups, real tutors - works really well for groups of 4 to 14 delegates. Anywhere in the world; course language English.

Please ask about private 'maintenance' training for Python 2, Tcl, Perl, PHP, Lua, etc.
TCL writing/reading to several files

Posted by buchtDJ (buchtDJ), 7 March 2003
For our thesis we need to write a TCL script for VHDL code so we can write and read to different files. For example: I want to read the files FileIn0 to FileIn100 and process them with VHDL and then output them to FileOut0 to FileOut100. We wish to use loops so we don't have to make the outputfiles ourselves. Is there anyone who can help us. We never worked with TCL scripts before.

Thank you

Here's a starter ... the following code copies 101 text files according to your example.   You should extend it to check whether the file opens work by testing the return value (that's a bare minimum),  and you'll want to add in your processing too.


for {set filenum 0} {$filenum <= 100} {incr filenum} {
       set fhi [open FileIn$filenum r]
       set fho [open FileOut$filenum w]

       while {[gets $fhi line] > -1} {
               puts $fho $line
