- Error Messages
- :LINK:
- The linker is used to link assembled, Compiled programs modules
- together, load them into memory, and begin execution if desired. The
- program modules can come from different sources Some of the sources are
- BASCOM
- COBOL
- FORTRAN
- ASSEMBLER
- RPG
-
- :LINK:
- The format for the involk of Linker is
-
-
- LINK <filename1.ext/s,filename2.ext/s,....>
-
- where filename stands for Disk drive letter followed by a colon
- followed by the absolute file name
-
- ext is used if the module extension is different than .rel
-
- /s stands for switch options.
- EXAMPLE of a link
-
- LINK MAIN,FORLIB/S,MAIN/N/G/E
-
- The first MAIN is the name of the module from the fortran compiler
- The FORLIB/S is the library of standard fortran routines that will
- be selected
- The MAIN/N/G/E means to name the .COM file MAIN and to save it on
- current disk then execute MAIN automatically.
-
- :LINK:
- SWITCH OPTIONS
-
- Each switch option is preceded by a /
-
- E .... Exit to operating system
-
- G .... Go start execution
- Start execution of the program as soon as the current command
- line has been interpreted.
-
- M .... Map all symbols
- List both all the defined globals and their values and all
- undefined globals followed by an asterisk.
-
- R .... Reset the linker
- Puts the linker back to its initial state. the /R is used
- to restart LINK if the wrong file was loaded by mistake.
-
- S .... Search file
- Search the disk file having the filename immediately preceding
- the /S in the command string, to satisfy any undefined globals.
- This is convenient for having the linker search a library file
- of musch-used routines.
-
- U .... List all undefined globals
- List all undefined globals as soon as the current command line
- has been interpreted and executed. Link defaults to this
- switch; therefore it is generally not needed.
- :LINK:
