# 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
# structures (like 'namespace eval', 'interp eval', 'if', 'while',
# 'switch', 'catch', 'for', 'foreach', etc.) have no absolute
# location. The command implementations execute such scripts through
# Tcl_EvalObjEx. Flag 0 causes it to use the bytecode compiler. This
# causes the connection to the context to be lost. Currently only
