Separate Processes

You can break a batch program into a requester and one or more servers. In a

Pathway environment, servers can have their own servers. A Pathway server can

create another process and communicate with it through a READ statement with a

PROMPT phrase (an HP COBOL extension).

For information about COBOL85 requester-server pairs, see Simple Server Example.

TNS User Library

If your program does not fit in user code space, you can put some of the routines in the

TNS user library. The routines will then execute in an additional code space called user

library space. User library space consists of one or more (a maximum of 16) separate

user library code segments of 128 KB each.

The system loader resolves references to routines in user library space at fixup. To

enable the system loader to fix up references to routines in user library space, you

must provide the name of the user library file (see Fixup).

Routines That Can Be Placed in the TNS User Library

The language in which a routine is written determines whether you can place it in the

TNS user library (whether it can execute in user library space):

(Routine Executes in TNS User Library Space)

HP COBOL Yes, if the ENV LIBRARY directive is specified

HP C Yes, if the ENV LIBRARY pragma is specified

FORTRAN Yes, but then it cannot have any COMMON, DATA, or SAVE statements

Pascal No

TAL Yes, if no global blocks are defined
