Some GDB commands have little use when debugging Modula-2 programs.
Five subcommands of set print and show print apply
specifically to C and C++: vtbl, demangle,
asm-demangle, object, and union. The first four
apply to C++, and the last to the C union type, which has no direct
analogue in Modula-2.
The @ operator (see Expressions), while available
with any language, is not useful with Modula-2. Its
intent is to aid the debugging of dynamic arrays, which cannot be
created in Modula-2 as they can in C or C++. However, because an
address can be specified by an integral constant, the construct
{type}adrexp is still useful.
In GDB scripts, the Modula-2 inequality operator # is
interpreted as the beginning of a comment. Use <> instead.
