Scroll Prev Top Next More

298 — 01-Jun-93

MK0.C: Allocate new system area of memory partition (sysbas) for storage of variable size file/isam buffers./ JRB

 

MK2C.C, MKX2.C: Use new variables as.maxfile/as.maxisam to determine max # files./ JRB

297 — 28-May-93

MK2C.C: Amend logic in [146] and [147] to take account of MAPIDA./ JRB

 

Also use new m1.SPEC_TYPE to determine if [p,pn] specified./ JRB

296 — 24-May-93

MK2C.C: Extend workaround in [146] to LOOKUP call./ JDM

 

Don't look in [,0] unless no [p,pn] specified./ JDM

295 — 10-May-93

MK2C.C: Simple workaround to look in ,0 if random or input file not found./ JDM

294 — 05-May-93

MK0.C: Force MDO.LIT processing if explicit `.DO' in command./ JRB

293 — 13-Apr-93

MK3.C: Support SCALE on bitwise logical operations./ JRB

 

AMSORT.C: Add binary mode operation to polyphase merge sort. (Needed for random files containing '\0' or '\n' characters)  JRB

292 — 07-Apr-93

AMSORT.C: Use `belt & braces' approach for available memory testing. (Microsoft C still has far pointer arithmetic problems)./ JRB

291 — 05-Apr-93

MK2C.C: Permit ISAM Plus file to be opened as RANDOM for analysis purposes and for Report Writer 3.2A index handling. ("IDA" - "DAT" extension mapping and special read logic)./ JRB

290 — 02-Apr-93

MK0.C: Prevent warnings as flookup() now returns a LONG./ JRB

 

MK2C.C: Pass no. blocks as a LONG in ALLOCATE - not INT. (Can allocate files > 65536 blocks now)./ JRB

289 — 30-Mar-93

MKX2.C: Clear exitcol on entrance to infld to fix TYPE )./ JDM

288 — 26-Mar-93

MKI.C: Use 512 byte working buffer while processing directory blocks (Speed improvement factor of > 7 !!!)./ JRB

 

Add small peephole optimizations to rest of code./ JRB

287 — 25-Mar-93

MK2C.C: Do not print leading zero in PRINT if fabs(number) < 1./ JRB

 

ISAM sequence checking now performed if LOKSER_ON set./ JRB

 

Force debuffer to disk if MICROSOFT_C defined and LOKSER_FORCE_WRITE set./ JRB

 

MK3.C: Incorporate previous 4-byte binary fix for 5-byte binary./ JDM

 

MKI.C: LOKSER sequence checking now performed if LOKSER_ON set./ JRB

286 — 23-Mar-93

MK2C.C: Fix obscure numeric formatting problem in PRINT./ JRB

285 — 17-Mar-93

MK2C.C: Fix problem with READ/DATA and SCALE on binary variables./ JRB

284 — 15-Mar-93

MK0.C: Input serial number as well as encryption key./ JRB

283 — 12-Mar-93

MK0.C: Set `forced extension default' in fspec2host() call when parsing `.LIT' command program name./ JRB
