EhBASIC update

Three small updates to EhBASIC fix UCASE$(), LCASE$() and USING$(). See here for details.

The version is now 3.52

Great! Thank you Lee! :)

I should adapt the new version to Kiwi. I went with an older EhBASIC because of incompatibilities with the unix68k assembler and my impatience to address these assembler directives.

Yes you should, there are quite a few improvements. 8^)= The number to string routine has been modified to output up to seven significant figures, IF..THEN statements can now have an ELSE section, there is a new USING$() function for formating number output as well as some bug fixes.

I went with an older EhBASIC because of incompatibilities with the unix68k assembler and my impatience to address these assembler directives.

If you let me know what the issues are I'll see what I can do to address them while keeping the source compatible with the assembler I use.

When I try to assemble the actual version with unix68k I get these errors:
Code: Select all
Line 686 ERROR: Invalid opcode

Unix68k doesn't know about ifeq, ifne, endc. But I didn't look deeper into this issue yet.

Well the number of errors matches but the line numbers are off by 201, however it looks like unix68k doesn't support any sort of conditional assembly so ..

If you want nonexistant variables to return zero or a null string comment out all the code in these blocks.

Code: Select all
 ifeq  novar
. . .
 endc

Or if you want nonexistant variables to return an error comment out all the code in these blocks.

Code: Select all
 ifne  novar
. . .
 endc

If you want a null return to an INPUT command to break program execution comment out all the code in these blocks.

Code: Select all
 ifne  nobrk
. . .
 endc

Or if you want a null return to an INPUT command not to break program execution comment out all the code in these blocks.

Code: Select all
 ifeq  nobrk
. . .
 endc

You'll also need to comment out all the ifeq, ifne and endc statements.

Oh, I forgot to mention that Unix68k doesn't find the include file. Thus I just c&p its contents.

Thank you for the clarification. I would prefer the error method as it prevents one from forgetting to initialize a variable.
