You can specify options in the LINK input fields and in the LINK environment variable. LINK reads the options set in the LINK environment variable before it reads options specified in LINK input fields. This priority has the following effects:
The option LINK considers to be first is the first one in the LINK environment variable, if set. The /NOLOGO option behaves differently depending on whether or not it is first. However, the /r option cannot be specified in the LINK variable and must be specified first on the command line.
An option specified multiple times with different values will get the last value read by LINK. For example, if /SEG:512 is set in an input field, it overrides a setting of /SEG:256 in the LINK variable.
For some options, if an option appears in the LINK variable and a conflicting option appears in an input field, the input-field option overrides the environment-variable option. For example, the input-field option /NOPACKC overrides the environment-variable option /PACKC.
