ments used. The resulting parameter list is shown in Figure 20. The first part of the figure shows the map of parameters passed to a BFX block module from the BFX send or receive control module. The second part shows the work area used by the block module. The meanings of the parameters in Figure 20 are described in the FORTRAN entry section. ====================================================================== Map of parameter pointers passed to a BFX block module ---------------------------------------------------------------------- 0 (0) ADDRESS 4 BBUF Address of block ---------------------------------------------------------------------- 4 (4) SIGNED 4 BBUFLEN Block length ---------------------------------------------------------------------- 8 (8) SIGNED 4 BBUFUBIT Unused bit count ---------------------------------------------------------------------- 12 (C) SIGNED 4 BDTMODE Datamode used for transfer ---------------------------------------------------------------------- 16 (10) SIGNED 4 BBUFLEV Delimiter level ---------------------------------------------------------------------- 20 (14) ADDRESS 4 BMSG -> 128 byte area for message ---------------------------------------------------------------------- 24 (18) SIGNED 4 BMSGLEN Length of returned message ---------------------------------------------------------------------- 28 (lC) SIGNED 4 BMSGLEV Severity of returned message ---------------------------------------------------------------------- 32 (20) SIGNED 4 BLCM Negotiated least common mult ---------------------------------------------------------------------- 36 (24) SIGNED 4 BMODE File MODE ---------------------------------------------------------------------- 40 (28) CHARACTER 8 BDDNAME DDNAME of file ---------------------------------------------------------------------- 48 (30) CHARACTER 64 BBPARM 64 bytes of BPARM text ---------------------------------------------------------------------- 112 (70) CHARACTER 8 BRMOD Alpha name of desired rec mod ---------------------------------------------------------------------- 120 (78) CHARACTER 64 BRPARM 64 bytes of RPARM text ====================================================================== Start of work area used by block module ---------------------------------------------------------------------- 184 (B8) SIGNED 72 BMSAVE Save area used to call rec mod ---------------------------------------------------------------------- 256(100) DOUBLE 8 BDUBL Doublework work for CVD ---------------------------------------------------------------------- 264(108) SIGNED 4 BRECMAX Max logical record size for file ---------------------------------------------------------------------- 268(10C) SIGNED 4 BRECNUM Count of records sent/received. ---------------------------------------------------------------------- 272(110) SIGNED 4 BHDRLEN Record protocol header length ---------------------------------------------------------------------- 276(114) BIT 1 BFLAGS Work flags 1... ....

====================================================================== Figure 20. Block module parameters Writing Job Submission Modules Job submission modules are designed for those installations that have other means than the BFXJS program to submit jobs to other hosts. The inclusion of user modules allows any means of programmable job submission to be employed by the installation. Job submission modules are designed to be written in Assembler language by an installation systems programmer. When the job submission module is called, it is passed a pointer to the completed transfer option list data structure in R1 (see Data Structures in “Appendix B. BFX Internal Summary" on page 77). It may obtain or generate a job from any source, and submit the job through any means available in the user programming environment. On return, it should set the TROLPRC code to indicate if the job submission was successful or not. Frequently, installations may want to modify or generate extra statements in the job submitted by the user, using the standard RMTJOB DD input and BFXJS job submission techniques. Rather than coding an entirely new JMODULE, it will frequently be easier to provide a new RMODULE to be used during the job submission process. This RMODULE merely needs to provide the job text to its caller one statement at a time, and may insert or modify records from the RMTJOB file as its logic chooses. If a record module is written in lieu of a new job submission module, it must be entered as a record module. MAN-REF-H211-05 Appendix A: User Modules Page 75
