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
|
|
|
