SINK Command

Use the SINK command to invoke a function but discard its result. SINK can discard

nonnumeric results as well as numeric ones.

Consideration

Use of the SINK command discards error indications returned by a function. Therefore,

the use of SINK is not recommended unless you do not need to know if an error

occurred. For example, if you want to purge a file but do not care if you try to purge the

file and the file does not exist, use SINK to discard any error that might occur.

Example

This command loads the TACL library file MYMACS into memory, but does not display

the list of variables that were modified:

14> SINK [#LOAD mymacs]

SINK [ text ]
