A clause is the fundamental grouping of Rexx syntax. Roughly, it is the unit of syntax that may exist independently on a single line without using semicolons or continuation characters.
The following Rexx program has four non-empty clauses:
/* This comment is part of an empty (null) clause */ input=arg(1) /* This assignment is the first clause */ do 10 /* .. second */ say input /* .. third */ end /* .. fourth */
A performance measure for Rexx interpreters and compilers is the rexxcps.rex program; results of running this on various platforms over the last 25 years are in the RexxCPS list.
