# reported command. The latter is required because otherwise the whole
# test case may appear in some results, but the result is part of the
# testcase. An infinite string would be required to describe that. The
# cutting-down breaks this.

# Procedures defined in scripts which are arguments to control

# 'switch', 'catch', 'for', 'foreach', etc.) have no absolute
