cache: Cache parameter files, or print the current cache list

Package: language

Usage

cache task [task ...]

Parameters

task: The name of a task whose parameter set is to be cached in fast memory.

Description

The cache command loads the parameters of a task in memory. The CL normally reads the parameters for a task from disk whenever the task is executed. Cacheing the parameters for frequently executed tasks can speed up execution significantly. This is particularly important when the tasks are called from within a loop.

If the cache command is entered without any arguments a list of the currently "cached" tasks is printed.

Examples

1. Cache the parameters for the tasks directory and page.

cl> cache dir page

2. Cache the parameters for the tasks called in a loop within the body of a procedure script. Note the use of command mode in the script.

begin
        cache ("alpha", "beta")
        for (i=1;  i <= 10;  i+=1) {
            alpha (i)
            beta (i)
        }
end

Bugs

The parameter cache should not be confused with the process cache associated with the prcache and flprcache commands.
