This python script does a little bit more than converting ANSi art to EBCDiC but the name is catchy.
This script will take any ANSi art you can find/create and convert it in to the HLASM/JCL you need to display the art in TN3270. Some great ANSi/ASCii art can be found at https://16colo.rs
ANSi2EBCDIC requires Python3 and the library SAUCE. Due to the SAUCE library not having a Python3 Pypi release right now, the installation is a bit messy.
You can install and run ANSi2EBCDIC like this:
$ git clone https://github.com/mainframed/ANSi2EBCDiC.git
$ cd ANSi2EBCDiC
$ python3 -m venv app
$ git clone https://github.com/tehmaze/sauce.git
$ (cd sauce && ../app/bin/python3 setup.py install)
$ app/bin/python3 ansi2ebcdic.py --helpThe output produced by this script will assemble and link your program and place it where it needs to go so you can use it in VTAM usstables (z/OS and TK4-) or just run it from TSO.
This script gives you multiple options and works on z/OS as well as Jay Moseley's Sysgen and TK4- (running on hercules). These options can be broken down as the following:
If you're running your own zPDT z/OS mainframe, or you just want to spruce up your corporate mainframe this option will take whatever ANSi art you pass it and convert it to the HLASM/JCL needed to make a valid USS Table for VTAM.
When generating a USS Table you need a place to allow user input. By default this script places the cursor, in red, at row 23, column 20 with a field size of 20. You can change these by supplying a row, column and color by specifying the following:
--colorthe color for the cursor, default is red--ROWthe row for the cursor, default is 23--COLthe column for the cursor, default is 20--inputhow wide the input area is, default is 20
For USS tables you need to supply a member name with --member, this should be the member name in your TN3270 parmlib BEGINVTAM (config file) in your TCPIP configuration.
BEGINVTAM
...
USSTCP MEMBER
ENDVTAM
replace MEMBER with your member name, the default is ANSIART.
You also need to supply a dataset with --dataset, this is where the assembled HLASM will be stored. It needs to be in your VTAM library. On zPDT/ADCD you can typically store it in USER.VTAMLIB. This setting is set in your VTAM start procedure under //VTAMLIB and the search order is top to bottom.
Once uploaded with either FTP or IND$FILE, you need to submit the job with submit in ISPF, then you need to refresh and reload the USS Table. To do this use the MVS command: vary tcpip,tn3270,obeyfile,dsn=user.tcpparms(tn3270), replace USER.TCPPARM(TN3270) with the location of your actual TN3270 settings. To do this on ADCD, in ISPF enter the command =sd and hit enter. Then type / hit enter, then enter the command vary tcpip,tn3270,obeyfile,dsn=user.tcpparms(tn3270).
This is for use on Jay Moseley's SYSGEN or the automated sysgen. This replaces the standard MVS VTAM screen with the ansi art supplied. This script will automatically generate the JCL you need to create your own VTAM netsol screen. Note: You must install the optional SYS2.MACLIBS for this to work. To install you can type INSTALL MACLIBS in TSO.
Unlike usstable, you don't need to supply a dataset name as the dataset use to store the compiled uss table is stored in SYS1.VTAMLIB(ISTNSC00). The source HLASM generated is stored in the member name supplied by --member in SYS1.UMODMAC.
When generating you need a place to allow user input. By default this script places the cursor, in red, at row 23, column 20 with a field size of 20. You can change these by supplying a row, column and color by specifying the following:
--colorthe color for the cursor, default is red--ROWthe row for the cursor, default is 23--COLthe column for the cursor, default is 20--inputhow wide the input area is, default is 20
Once you've uploaded (using FTP or IND$FILE) the JCL, submit it in TK4- with submit and run the following commands to refresh VTAM:
Shut down the services:
/Z NET,QUICK
/P SNASOL
/P JRP
Then bring the services back:
/S NET
/S SNASOL
/S JRP
This is for use on TK4- (or potentially any MVS 3.8j implementation but has only been tested on TK4-). This replaces the standard MVS TK4- VTAM screen with the ansi art supplied. This script will automatically generate the JCL you need to create your own VTAM netsol screen. It keeps the terminal ID/dat and time in the upper left/right of the terminal.
Unlike usstable, you don't need to supply a dataset name as the dataset use to store the compiled uss table is stored in SYS1.VTAMLIB(ISTNSC00). The source HLASM generated is stored in the member name supplied by --member in SYS1.UMODMAC.

If you don't want to change your VTAM terminals but instead just want to show off some amazing ANSI art (for example in a TSO exit, or for use with logon procs, or you just want to call it yourself) you can use the --tso argument.
This argument generates the HLASM/JCL you need to be able to call an assembled program from TSO and display the art to your 3270 terminal.
Since the JCL for TK4- and z/OS are different you need to supply either --tk4 or --zos when using this argument.
By default the script stores the assembled output in ANSI.ART(ANSIART). To change this use the --dataset and --member arguments. The dataset needs to be a previously created PDS/PDSE before you place your art in it.
Once the script is done you can upload your HLASM/JCL with FTP or IND$FILE and submit the JCL. To view the art, in TSO use the command CALL ANSI.ART(ANSIART) using the --dataset and --member if you changed those.
By default this script will display the HLASM to the terminal. If you want to save it to a file use the --file argument.
By default most TN3270 emulators only support the colors: white, red, green, yellow, blue, pink, and turquoise. On some emulators, for example x3270 you can get extra the extra colors: black, deep blue, orange, purple, pale green, pale turquoise, and grey.
If you know your terminal supports the extra colors use the argument --extended to enable them. If the ANSi you are your using uses the default/dim colors you'll want to enable this feature.
Example, here's the original art: https://16colo.rs/pack/5th-9704/LK-IRID1.ANS
Default Graphics
Extended Graphics
If you want to see what the script is doing behind the scenes there is a --debug argument. Be warned, however, that this debug output is very verbose.
Example output (with debuging enabled):
./ansi2ebcdic.py --dataset ANSI.ART --member IRIDIUM --tso --tk4 --file iridium2.jcl --jobname iridium --extended --debug ./LK-IRID1.ANS

You will run out of addressability if the ANSi art is too complicated. This could be fixed in a future version.
