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.
printing current line number

How do I  puts current line number?
I could find 'info script' to get the script name.  I could not find command to get the line number.

info cmdcount

will tell you the number of commands you've interpretted, but there's nothing that I know of to tell you the line number.   That's quite logical, as proc commands store a procedure and the original file numbering is not retained at that point.

Thanks for your reply.

hmm.. In that case how does $LINENO work fine for shell script?

Posted by admin (Graham Ellis), 29 September 2006
Because Shell script is a different language that keeps track of which line it's at.   There's a different "balance" between the languages - shell is a scripting tool in which you can define functions, but Tcl is a full procedure based language where named blocks of code that are stored are inherrently much more important.
