Welcome to the JALv2 homepage. JALv2 is a rewrite of
Wouter van Ooijen's famous Just Another Language.
JALv2 adds the following enhancements to the original:
More JAL bits and libraries can be found:

Release history:
Lastest release files (JALv2 2.4d):
Bleeding edge files. Warning -- these are probably in the midst of being tested, and some features may not work. Always look at the README file to see what changes have come in! The version is always one higher than the last release.

Severity is
|
| ID | Severity | Version | Description | Fixed |
|---|---|---|---|---|
| B00038 | medium | all | assignment to multi-bit variables isn't shifting the result into the correct bits. | 2.4d |
| B00037 | high | 2.4c | division fails due to invalid assumptions about subtraction | 2.4d |
| B00036 | medium | all | Inline parameters that are specifically positioned are incorrectly replaced with locals. | 2.4d |
| B00035 | high | all | compiler crashes with lookup tables on 16 bit cores | 2.4c |
| B00034 | request | 2.4 | ability to program the ID bytes | open |
| B00033 | request | 2.4 | repeat..until loop | 2.4b |
| B00032 | request | 2.4 | `exit loop' request for all loop types | 2.4b |
| B00031 | medium | 2.4 | inline assembly might incorrectly use bank and page operators on 16 bit cores | 2.4b |
| B00030 | request | 2.4a | Would like pascal - styled record support | open |
| B00029 | high | 2.4a (probably all) | The simple construct `forever loop end loop' will hang the compiler | 2.4b |
| B00028 | low | 2.4a | Under some circumstances the optimizer might issue ``opt pass has gone infinite'' This will lead to slightly unoptimized code but the resulting program should run correctly. | 2.4b |
| B00027 | medium | all | wrong registers used when receiving the result of a function in an inlined function | 2.4a |
| B00026 | medium | 2.4 | Loop optimization bug with nested IFs | 2.4a |
| B00025 | medium | 2.4 | Occasionally the hardware stack computation is off. | open |
| B00024 | med | 2.4 | Compiler is re-using state variables that are in use in some cases. | 2.4a |
| B00023 | low | 2.3 | Alaised variables in inline functions don't work | 2.4 |
| B00022 | low | 2.3 | Passing multiple filenames on the command line crashes the compiler | 2.4 |
| B00021 | low | all | Cannot alias a pseudo-variable | 2.4 |
| Workaround: create a dummy variable with the same name as the pseudo-variable. | ||||
| B00020 | medium | 2.2.3a | indexing into a multi-byte lookup table doesn't work | 2.4 |
| B00019 | medium | 2.2.3a | nest 'if...end if' directives get confused if an `else' follows an `end it' | 2.2.3b |
| B00018 | medium | 2.2.3a | long jump tables generate incorrect code | 2.2.3b |
| B00017 | medium | 2.2.3a | `pragma interrupt fast' doesn't generate any code | 2.2.3b |
| B00016 | medium | 2.2.3 | An empty IF block immediately followed by procedure or function call will generate bad code. | 2.2.3b |
| B00015 | medium | all | A temporary is used by a FOR statement (eg, FOR x + 1 LOOP) it will likely be overwritten somewhere in the block. | 2.4 |
| B00014 | low | all | Compiler leaks memory like a sieve | open |
| B00013 | low | 2.2.3 | When only CONST arrays are passed into as flexible arrays, PCLATH<6> gets set | 2.2.3b |
| B00012 | medium | 2.2.3 | Bad code is generated when the result of a flexible array read is passed directly to another function | 2.2.3b |
| B00011 | request | 2.2.3 | Constant strings should be able to be passed directly to a procedure with flexible arrays, eg write_string("hello") | open |
| B00010 | request | 2.2.3 | Should be able to pass psuedo-arrays to a procedure with flexible arrays | open |
| B00009 | request | all | 16-bit support | 2.4 |
| B00008 | request | all | variables should be allowed to be placed in EEPROM | open |
| B00007 | request | all | Inline assembly should be able to get the address of a variable | closed |
| This simply isn't possible with the current compiler because the compiler has no idea where a variable will be placed until long after the inline assembly has been parsed. For this to work the compiler would first need to emit assembly code, then a second pass to compiler the assembly, or alternately only emit assembly and have MPLAB complete the process. | ||||
| B00006 | mild | 2.2.3 | If -bloader is used the page and data bits may not be set correctly | 2.2.3a |
| B00005 | mild | 2.2.3 | Flexible strings, when passed a non-const array would not set _irp correctly | 2.2.3a |
| B00004 | mild | 2.2.3 | spurious `requires boolean expression' | 2.2.3a |
| B00003 | mild | 2.2.3 | multi-byte decrement doesn't work correctly in the self assignment case (eg, x = x - 1) | 2.2.3a |
| B00002 | med | 2.2.3 | const shift right and shift right arithmetic does not work correctly (eg, x = 5 >> y) | 2.2.3a |
| B00001 | low | 2.2.3 | jalv2 should show help if no file is present, or if and of "/help", "/h", "/?" are present | 2.2.3a |
