#pragmas with the class name link_option are used to specify linker options. These #pragmas may only occur in project files.
The following link_option #pragmas are available:
#pragma link_option(case ⇒ on | off )
#pragma link_option(decode ⇒ on | off )
#pragma link_option(link⇒ <;string>)
#pragma link_option(map ⇒ on | off)
#pragma link_option(overlay ⇒ on | off )
#pragma link_option(pack ⇒ on | off )
#pragma link_option(shift ⇒ num)
#pragma link_option(share_const ⇒ on | off)
#pragma link_option(icon ⇒ iconname)
A pragma can be used in the Project language, C++ code, Modula-2 code, or Clarion code. Some only work in certain places. A 'P' to the right of the pragma indicates it can be used in the Project language, a 'C' indicates it can be used in C++ code, a 'M' indicates it can be used in Modula-2 code, and a 'W' indicates that it can be used in Clarion code (CLW files).
#pragma link_option(map ⇒ on | off) p
Controls whether a map file is generated with information about segment sizes and publics etc. The default is to create a map file.
#pragma link_option(case ⇒ on | off ) p
This #pragma controls whether the linker treats upper/lower case as significant when linking. The default is case⇒off.
#pragma link_option(pack ⇒ on | off ) p
This #pragma controls whether segments are packed together. The default is pack⇒on.
#pragma link_option(decode ⇒ on | off ) p
This indicates whether the linker should produce decoded names in the MAP file, as well as their public symbols. The option is set to on if any C source files are included in a project, otherwise off.
#pragma link_option(shift ⇒ num) p
This specifies the segment alignment shift count for new-format executables. The default is 4, indicating that segments are aligned on 16-byte boundaries.
#pragma link_option(link ⇒ <;string> ) p
This specifies the project system command to execute on #dolink.
#pragma link_option(share_const⇒ on | off) p
This pragma controls whether the 16-bit linker commons-up identical constants. The default is on, making the exe file smaller, but C programmers may want to turn it off if they are relying on constants having different addresses.
#pragma link_option(icon ⇒ iconname) p
This pragma specifies the name of the application icon file (icon ⇒ MyIcon.ico).
