Chpop(name) Last updated: 17. Oct 2026

Removes the last level of the counter: "2.1" becomes "2". Removing the only level leaves an empty value.

The counter is a text value of numbers separated by dots, such as "2.1", and is written out with #name#. The function itself returns an empty string, so #chstep("c")# writes nothing. The function names are lower case: chinit, chstep, chdestep, chpush, chpop.

Parameters

Name	Type	Description
name	string	Name of variable to store chapter counter in.

Returns

Nothing, just removes a level from the counter.

Example

Code example (#JS)

#JS is mixed HTML (or other text file) with inline JavaScript with # starting and ending each inline statement.

#{
    chinit("counter1");
    chstep("counter1");
    chstep("counter1");
    chpush("counter1");
    chstep("counter1");
    chstep("counter1");
}#

Counter value is: #counter1#

#{
    chpop("counter1");
}#

Counter value is: #counter1#

Output

The #JS code above produces the output shown below:


Counter value is: 2.2


Counter value is: 2
