include vmm.inc
mov eax, Default ; default value
mov ecx, Places ; number of digits after decimal point

The Get_Profile_Fixed_Point service returns the value of a
fixed-point-number entry in the SYSTEM.INI file. The Profile and Keyname
parameters specify the section and entry to search for.
This service is only available during initialization.
Parameter Description
────────────────────────────────────────────────────────────────────────────
Default Specifies the default value to return if the entry is not found
or has no current value.
Places Specifies the number of digits after the decimal point to
convert. If fixed-point number has extra digits, the service
ignores them.
Profile Specifies a null-terminated string identifying the section in the
SYSTEM.INI file to search. If Profile is zero, the service
searches the [386Enh] section.
Keyname Points to a null-terminated string identifying the name of the
entry to search for.
Return Value
If the carry and zero flags are clear, the specified entry is found and is a
valid fixed-point number. In this case, the EAX register is set to the
normalized value of the number; the actual value is computed as EAX * 10 **
(-Places).
If the carry flag is clear and the zero flag is set, the specified entry
exists but has no corresponding value. If the carry flag is set, the entry
cannot be found or the entry does not represent a valid fixed-point number.
In these cases, the EAX register is set to the Default value.
Comments
A valid fixed-point number is a decimal number that consists of an integer,
a fraction, or a combination of integer and fraction. The integer can be any
combination of decimal digits, and may be preceded by a plus sign (+) or a
minus sign (-) to indicate a positive or negative fixed-point value. The
fraction can be any combination of decimal digits but must be preceded with
a decimal point (.).
