compilation_date
Compilation date. Here YYYY means the number of a year, MM means a month number, and DD means a day number.
compilation_date : string = "YYYY-MM-DD".
compilation_time
Compilation time. Here HH means hours, MM means minutes, and SS means seconds.
compilation_time : string = "HH:MM:SS".
compiler_buildDate
Build date of the compiler.
compiler_buildDate : string = "YYYY-MM-DD HH:MM".
compiler_version
A compiler version. This value depends upon the compiler version.
compiler_version = 6003.
maxFloatDigits
Defines the maximal value of "digits", which is supported by the compiler.
maxFloatDigits = 16.
null
A constant of type pointer with the value 0.
null : pointer = uncheckedConvert(pointer, 0).
nullHandle
A constant of type handle with the value 0.
nullHandle : handle = uncheckedConvert(handle, 0).
invalidHandle
A constant of type handle with the invalid (for a handle) value -1.
invalidHandle : handle = uncheckedConvert(handle, -1).
platform_bits
Defines the digital capacity of compilation platform.
platform_bits = 32. or platform_bits = 64.
platform_name
Defines the target platform name.
platform_name : string = "Windows 32bits". or platform_name : string = "Windows 64bits".
