Ed Liss' BASIC370 Interpreter

Added On 07/05/2025:  Ed Liss sent to me an update of his BASIC360 interpreter/compiler.  With this major upgrade to his code, he is renaming it to BASIC370 version 1.0.0. 

Download the archive downloads/archives/basic370.v100.tar.gz [MD5: 0e6d04b2331a5ef12c60984948e2c2bc], which contains an AWS tape image, a jobstream to reload the datasets, and a PDF document containing a very detailed manual for using BASIC370.  

The jobstream may require modification for your system; note lines two through six of the restore jobstream:

//RESTORE PROC HLQ='HMVS02', <- HIGH LEVEL QUALIFIER 
// TUNIT='3380', <- TARGET DEVICE 
// TVOLUME='PUB000', <- TARGET VOLUME 
// LOADLIB='SYS2.LINKLIB', <- LIBRARY FOR LOAD MODULE 
// PROCLIB='SYS2.PROCLIB' <- LIBRARY FOR PROC 

• HLQ specifies the high level qualifier of the dataset names for the six datasets which contain the source, samples, libraries, etc.,
• TUNIT specifies the DASD unit type to which the six datasets are to be restored,
• TVOLUME specifies the DASD Volume Serial to which the six datasets are to be restored,
• LOADLIB specifies the library to which the BASIC370 load module is to be restored, and
• PROCLIB specifies the library to which the BASIC370 PROC is to be restored.

Following restoration of the datasets from the tape, it is recommended that you edit the restored catalogued procedure, BASIC370, to verify lines two, twelve, and thirteen are correct for your installation:

-line  2- // LIB='HMVS01.BASIC370.BAS', <- VERIFY FOR INSTALLATION
-line 12- //STEPLIB DD DISP=SHR,DSN=SYS2.LINKLIB <- VERIFY FOR INSTALLATION
-line 13- // DD DISP=SHR,DSN=SYS1.PL1LIB <- VERIFY FOR INSTALLATION

• line 2, LIB= specifies the library from which stored BASIC statements are retrieved and saved,

• line 12, specifies the library to which the BASIC370 load module was restored (LOADLIB parameter in the RESTORE PROC above)

• line 13, specifies the library which contains the library routines for the MVT PL/1 compiler

** Note ** You do not need to install BASIC370 if you have installed SYSCPK, because BASIC370 is already installed on SYSCPK.

Output from a run of the BASIC370 demo program from the sample dataset may be viewed here:  basicdemo.pdf.

I hope that you have found my instructions useful.  If you have questions that I can answer to help expand upon the information I have included here, please don't hesitate to send them to me:
