NAME
sysinfo - return a calc #define value
SYNOPSIS
custom("sysinfo" [, infoname]);
TYPES
infoname string or int
return int, string or null
DESCRIPTION
This custom function will return the value certain selected #define
values. The infoname arg must be a string that matches the given
#define name. For convenience, the case infoname does not matter,
so "baseb" and "BASEB" refer to the same #define value.
The return value is either an integer or a string depending on
the type of #define selected. If infoname is unknown, NULL is returned.
If no infoname is given then a list of infonames and meanings
are printed. In this case, null is returned.
If infoname is a number, then it is interpreted as follows:
0 print all infonames and meanings (same as no infoname)
1 print all infonames and values
2 print all infoname meanings and values
