 Subj: 68KFORTH+ VER 2.2, 3.0        Status: PUBLIC MESSAGE

 Hi Ray,
 It appears there is a problem with the old version of the metacompiler.
 ver 2.2 for 68k FORTH+ ( uses 32 bit token table, 16 bit word ptrs )
 Will not generate .IMG file for size over 64K, Error message returned
 when writing object file is " can't write object file ". Disk space
 is ~ 8 Mb free on 110 Mb drive. size of .IMG file written is
 Actual size of image - 65536 and the first part of the image file
 appears ok. I guess a 16 bit pointer was used to maintain the object
 code buffer area. I am unable to use the latest versions 3.0 due to some
 restrictions on the size of the image.i.e. Using 16 bit word pointers
 appears to restrict total code space to 64Kb.
 Questions:
 1) Is it possible to fix?
 2) Will LMI Assist us in resolving this problem?
 3) Is version 3 really restricted to 16 bit relative addressing
 4) Know of and other workarounds?
 Our application is currently in the 60-70 Kb range ( object )
 and we planned on dding major inhancments to the system. I expect the
 system to eventually reach the 100-150 Kb Before the next release.
 Were really between a rock and a hard place at the moment, I have other
 projects coming on line in a few weeks and have to get this out the door
 before all my other schedules start to slip. We also have two other
 projects ( one for the Air force and one for the British Navy ) that
 will be using the Ver 2.2 imbedded FORTH.
 If you can't come up with a workaround, Would it be possible ( with
 the proper non-disclosure agrement ) to aquire the meta compiler source
 for version 2.2? I Will have my boss contact you after I receive your
 reply.   Thanks Again,
