#985 Accept Mouse and display anomalies
This should probably go under the ticket: #588 Accept/display bugs?
I am experiencing some problems with accept and mouse implementation.
I am using esqlOC in the precompile step and I have -lpdcurses in the compile step.
There are two anomalies that are happening.
First the mouse problem seems like the Special Names CURSOR IS WS-CURSOR is only updating on every fourth click and sometimes only on the eighth click? This is happening on left clicks, right clicks and the wheel clicks. The display statements tell me this. This version of the code that I am posting here actually has many more display statements that I have removed here for clarity. So, I know the path being taken on mouse clicks and function key presses are correct. Can anyone tell me why it seems only the fourth or eighth clicks are being recognized?
The other anomaly has to do with the accept statement. For some reason, the accept at 2417 location changes to the at row/col of the last 'display at' statement that executed? As you can see in this code, I had to add 'display A2-AN at 2417' to put the accept location back to where it is supposed to be. Is this normal? Has anyone else experienced this?

Not being an expert on the usage of the mouse but you have not specified the copy lib for the statuses for screen/mouse so include in WS :
This copy book sits by default in the gnucobol compiler sources in folder copy.
Now look in that copybook under "*> Exception keys for mouse handling" where you will find the codes available such as :

Change you init. code in PD to match as needed.
I apologize. The program has the screenio.cpy hard coded in the program. For some reason the COPY statement is not working. Probably, I am setting the wrong the environment variable to search for copybooks? I have two variables set and neither is working so I just copied the screenio.cpy contents into my program.
SET "COB_COPY_DIR=%apphome%\cobcpy"
SET "COBCPY_DIR=%apphome%\cobcpy"

In my .bashrc file I have (among others) :
export COBCPY=~/cobolsrc/ACAS/copybooks
export COB_SCREEN_ESC=YES
export COB_SCREEN_EXCEPTIONS=YES
export COB_LIBRARY_PATH=~/bin
export PATH= etc, etc
export TMPDIR=~/tmp
export DB_HOME=.
Note that the export commands do NOT have any quotes but in any event what is var apphome set to prior to these SET commands AND have you verified that they are set correctly such as by doing a set | less and checking.
I have not seen anything using COB-ALLOW and COB_AUTO in gnucobol presets. You must only be using what is allowed in GnuCobol and where used before migration remove all MF one's not shown as supported.
Read the Programmers Guide or Reference along with the content of file NEWS that is in the distributions of GC. The manuals you can get from the SF website at :
https://gnucobol.sourceforge.io/guides.html under heading of GnuCOBOL Documentation.
Check the usage of ALL WS vars to confirm that you are using them correctly under GnuCobol and check the report for any warnings or errors. This can be produced when compiling by running cobc -x myprog.cbl -T myprog.prn
Then look at myprog.prn, although running cobc should be showing any warning error messages .
Response times for status on ACCEPT / DISPLAY should occur immediately although use of Escape can take up to half a second for some reason at least on my system under Mageia v9 X64 Linux using a AMD FX8350 8 core cpu.
The interesting question is: do we have a reason to not switch the default values of those two SCREEN configuration options?
Any thoughts @btiffin?

Oh and for the preset: you can use the computed value and set/export that to COB_MOUSE_FLAGS.
Thanks for the help guys. Most of this is my own fault being a GNCobol newbie. I worked on the COPY problem and discovered that COPY works if it is in or after column 12.
The only anomilie I see now is when I have a DISPLAY at XXYY within the Accept statement (ACCEPT - END-ACCEPT), the DISPLAY at XXYY changes the ACCEPT to now ACCEPT AT XXYY. I have to follow the DISPLAY AT XXYY with another DISPLAY at 2417 so the ACCEPT entry box is where the ACCEPT Statement at should be at 2417.
Please confirm that this bug report can now be closed.
