Week 4 presentation! This week we will cover editing and the use of the on-board tools provided, SEU and PDM.

2 Entering source code

3 Enter Source Code using SEU SEU can be used for entering many types of source code e.g. DDS Data Definition Specification C programs CL programs… SEU needs the source file name, the member name and the source type.

4 SEU: Source Entry Utility STRSEU or use F6 in PDM to create a new member. Remember to specify TYPE attribute when starting Take note of the function keys available in a editing session e.g. Browse/Copy function (F15) They can be used to browse a compile listing They can be used to copy from another member.Find/Change option (F14) They can be used to find occurrences of words

5 Determine the “file” usage The source attribute type: –tells SEU what type of source you are creating e.g. TXT, PF, LF, CL, etc –Determines which SYNTAX checker to use –Determines which COMPILER to use when creating the object.

6 Start Source Entry Utility STRSEU or STRPDM (WRKLIBPDM or WRKMBRPDM or WRKOBJPDM) for CL program specifications Type choices, press Enter.

9 SEU Editor SEU has built in editor SEU==>________ command line Line commands: –C copies a line CC…CC copies a block –M moves a line MM..MM moves a block –I inserts, In inserts n lines, IP inserts and prompts –D deletes, Dn deletes n lines –A = after, B = before the target for move/copy

12 Internally v.s Externally declared files When created INTERNAL vs. EXTERNAL Single field (alphabetic) equal to record length Fields Defined within (internal to) programs. Record substructure (Fields) NOT globally accessible by other programs / utilities One or more fields defined in a DDS source file File structure generated externally from a source member Globally accessible by all programs and utilities

13 Compiling the Source Code CRTPF command or Option 14 in PDM takes the source code and creates the object i.e. the CL executable program or an ”externally” declared data file

17 How do you know if the compile worked??? An output file is created with each compile (the compile listing) which tells you what happened. READ it! Where is that output file?? In your output queue!!

18 Compile Errors Make sure the compile worked! The PDM user option SP shows you your spooled compile listing AND if there are errors, a joblog. If errors, return to SEU, use F15 then option 2 for spool files. The system will bring up your compile listing in the bottom half of a split window.

19 Compile Errors cont’d On the lower window command line, enter F *err (find errors) Pressing F1 with the cursor on the message will give you an explanation of the message Use F12 to return to browse window and press F16 to repeat the find errors command. Check out the warning messages also.
