COBOL Manual for TNS/E Programs (H06.08+, J06.03+)
Removal Required
Replace any references to TNS/R libraries with references to the analogous TNS/E libraries:
With ...Replace ...
ECOBEX0NMCOBEX0
ECOBEX1NMCOBEX1
ECOBEXTNMCOBEXT
References to TNS /R libraries can appear in these contexts:
• CONSULT directive
• SEARCH directive
• File-mnemonic clause of the SPECIAL-NAMES paragraph
• OF or IN clause of the CALL or ENTER statement
Possible Changes Required
• Directives
• RENAMES Clause
Make any necessary changes to these items before compiling your HP COBOL source program
with the ECOBOL compiler.
Directives
• CONSULT Directive
For the NMCOBOL compiler, each object-name in a CONSULT directive must designate a
TNS/R native object file (otherwise the compiler reports an error).
For the ECOBOL compiler, each object-name in a CONSULT directive must designate a TNS/E
native object file (otherwise the compiler reports an error).
For a complete description of this directive, see CONSULT and NOCONSULT (page 544).
• OPTIMIZE Directive
The NMCOBOL compiler handles OPTIMIZE 2 as if it were OPTIMIZE 1, because native
COBOL does not support global optimization. The ECOBOL compiler handles OPTIMIZE 2
as the COBOL85 compiler does.
