Name

incr0 — increment a variable or set it to 1 if nonexistent.

Synopsis

incr0 ?varname? ?num?

Description

Increment a variable varname by num. If the variable doesn't exist, create it instead of returning an error.

[Note]Note
incr0 functionality is provided by the native incr in Tcl >= 8.5, therefore this command is deprecated and kept as an interpreter alias only for compatibility. As such incr0 wasn't moved to the ::rivet namespace and it will be removed in future versions of Rivet.
