allocation. The symbol may be used as a variable name.

38.10. Macros
Macros do not require explicit dereferencing of arguments (i.e. \ARG).
During macro expansion, the macro parameters are converted to subsyms. If the number of arguments
passed the macro invocation exceeds the number of parameters defined, the last parameter is assigned
the string equivalent of all remaining arguments. If fewer arguments are given than parameters, the
missing parameters are assigned empty strings. To include a comma in an argument, you must enclose
the argument in quotes.
The following built in subsym functions allow examination of the string value of subsyms (or ordinary
strings). The arguments are strings unless otherwise indicated (subsyms passed as args will be replaced
by the strings they represent).
$symlen(
str
)
Returns the length of
str
.
$symcmp(
str1
,
str2
)
Returns 0 if
str1
==
str2
, non zero otherwise.
$firstch(
str
,
ch
)
Returns index of the first occurrence of character constant
ch
in
str
.
