Welcome to the forum.
If you step back a little and look at your first post from a slightly different angle, you will agree that you have not given us TOO much to work with. On top of the usual ones like "What's your OS? shell?" , quite some questions are left open, as
- is THAT the parameter file structure: $variable= value? Sure about the $ sign?
- WHAT is the date format - ddmmyyyy or mmddyyyy? (i.e. WHAT should we increment?)
- is that a task for a script or better done manually?
- how often should it run? year in and year out?
- would it need month and year increment as well, then, and leap years considered?

__________________________________________________________________________________________________________________________________________________
NAME
incr - Increment the value of a variable
SYNOPSIS
incr varName ?increment?
_________________________________________________________________
DESCRIPTION
Increments the value stored in the variable whose name is varName. The value of the variable must be an integer. If increment is supplied
then its value (which must be an integer) is added to the value of variable varName; otherwise 1 is added to varName. The new value is
stored as a decimal string in variable varName and also returned as result.
Starting with the Tcl 8.5 release, the variable varName passed to incr may be unset, and in that case, it will be set to the value incre- |
ment or to the default increment value of 1.
EXAMPLES
Add one to the contents of the variable x:
incr x
Add 42 to the contents of the variable x:
incr x 42
Add the contents of the variable y to the contents of the variable x:
incr x $y
Add nothing at all to the variable x (often useful for checking whether an argument to a procedure is actually integral and generating an
error if it is not):
incr x 0
