Linking Mixed-Language Programs

Overruling the Run-Time Consistency Check

The run-time consistency check can be overruled by the option 

-set

 

float_lib_overrule on

. If you overrule the consistency check, the operating 

system allows a floating-point inconsistency between the user library and the program. 
If you do not set 

float_lib_overrule

, and there is an inconsistency between the 

program file and user library, the operating system generates an error code and does 
not run the program.

If the 

float_lib_overrule

 is specified more than once by either the 

-set

 or 

-change

 option, all occurrences except the last one are ignored. The 

float_lib_overrule 

attribute can be changed only for loadfiles. An error occurs if 

an attempt is made to change the value of this attribute for linkfiles.

Linking Mixed-Language Programs

When linking mixed-language programs that use IEEE floating-point format, specify the 

-set

 

floattype

 

IEEE_FLOAT

 option.

For example, suppose that you have a mixed-language program composed of the 
following modules:

•

A C module that uses IEEE floating-point format

•

A COBOL module that does not use floating-point format but is marked by the 
COBOL compiler as 

TANDEM_FLOAT

When you link the modules together, you can do either of the following:

•

Use the 

-set floattype

 

IEEE_FLOAT

 option to set the floating-point type of the 

output object file to IEEE floating-point format.

•

Use the 

-change

 command to change the floating-point type of the COBOL object 

file to 

NEUTRAL_FLOAT

.

Example 2-11

 links a mixed-language program that uses IEEE floating-point format. 

The native C object file named COBJ uses IEEE floating-point format and the pTAL 
object file uses Tandem floating-point format. (pTAL supports only Tandem floating-
point format.) If this 

nld

 command did not include the option 

-set floattype 

IEEE_FLOAT

, 

nld

 would issue error messages because of the mismatch between 

Tandem and IEEE floating-point formats. Because this 

nld

 command does include the 

option 

-set floattype IEEE_FLOAT

, 

nld

 issues a warning message about the 

mismatch and builds the loadfile MYEXEC. CRTLMAIN (a linkfile) and the LIBCOBEY 
file (an Obey command file) are standard items required when linking C programs.

Example 2-11. Linking a Mixed-Language Program With IEEE Floating-Point 
Format

nld $system.system.crtlmain cobj ptalobj -obey &
  $system.system.licbobey -set floattype ieee_float -o myexec
