The following notes refer to the sample EXEC procedure shown above.
1. The output of the DSERV command is spooled to your virtual card
reader and is read in as $ESER EXEC. 2. The $ESER EXEC file is copied, edited, and formatted as a CMS EXEC file. All DSERV header and trailer lines are deleted.
3. If you wish to delete any of the generated ESERV commands, enter
any nonblank character. If you do not wish to delete any ESERV commands (or after you have deleted them), enter a null line.
4. Stack the remaining lines of the $ESERV EXEC in the console stack. 5. Read a line from the console stack and check that the first letter
begins with E (for ESERV). If not an E, ignore the line and read
the next one.
6. If it is an E, create a DSPCH fn for this macro. Note.;,. PUNCH or DSPLY may be substituted for DSPCH. Appendix G: Sample EXEC Procedure for Copying DOS/VS Macros 445

7. Execute the ESERV command. The de-edited macro is spooled to your
virtual card reader.
8. Read the macro file onto the CMS disk.
statement.
Delete the CATALS 9. Add the macro to the indicated CMS macro library.
For a large macro library, the ESERV process may take a substantial
length of time, up to several hours.
For a detailed description of the ESERV command, refer to the VML31Q CMS Command and Macro Reference. For more information on how to use the ESERv--Command: -See- "Appendix D: Sample Terminal Session for DOS Programs" in the !M/31Q For a detailed description of the DOS/VS ESERV control refer to the !Q Assembler, Order No. GC33-4024.
