You say : "Hey! What's new in this version ?"
I say ...
-----------------------------------------------------------------------------
24/08/96 * PPC 1.00 Public Beta 3
Changed/News:
■ Now use PPC.INI to retreive default config (for example library
path, or user variable generation on/off by default)
■ Big changes in the command line because of the INI file!
Now makes a difference between switches & options. Switches are
used with a leading "+" or "-" to turn on or off the corresponding
feature. Options are always following a "-".
Type PPC alone for more.
■ Changed a bit the error message (differencing declarations and
expressions)
■ Added a more accurate error message when trying to redeclare
a user function/procedure with an internal user/function name
■ Added handling of subrange expressions in Case :
Select Case A
Case 5..10 ; Instead of Case 5, 6, 7, 8, 9, 10
End Select
■ Changed handling of Elseif structure to make it more compatible
with PPLC :
This structure (PPLC specific until this version) is now
correctly parsed.
If (expr) Then
...
Elseif (expr) (then?) <- THEN is optionnal
...
Endif
Simple Endifs are simply treated with an Else following
a new simple If statement :
If (expr) Then
Else If (expr) do stuff <- this statement is NOT
Endif a 'else' then 'if (exp) ...'
but a true 'else if' (exp) ...
■ Changed internal handling of labels & gotos, now can be anything
including reserved words.
■ Added Frontier-specific hearder if using Frontier-specific
statements/functions.
■ Added the following Frontier-specific statements :
- Abort
- GetMsg
- Leave
- DPrint
- DPrintLn
- DCls
- DAnsiPos
- DRestScrn
- DSaveScrn
- DGetX()
- DGetY()
- DScrText()
They are, or course, NOT handled by PCBoard, and using them
will create a Frontier-specific PPE.
■ Added handling of "=>" , "=<" and "=!" which are alias for
"<=", ">=" and "!=".
■ Added display of filename in error message (this is needed since
you can #include files).
■ Library format changed a bit, recompile your libraries!
■ New version of PPLIB, the Lib Viewer, it now handles 1.02 Libs,
as well as 1.01.
■ Added command line switch +o to select the alternate console output
style (PPLC-like). This allows PPC to work with PowerPPL (althought
you should get the last PowerPPL which also has a minor change to
better handle PPC)
Fixed:
■ Fixed an ENORMOUS bug : strings were optimized case insensitively!
"Hello" were equal to "hello" ! fixed.
■ Fixed parsing of :
If (expr) Then Select Case
(thnx Hicks!)
■ Fixed parsing of :
If (expr) Then statement
statement
Else statement
statement
Endif
While (expr) Do statement
EndWhile
■ Fixed parsing of the '*' char in certain circumptances (appeared
only since beta2)
■ After returning from an included file to the parent source file,
compiler was missing a line, fixed.
■ Error after 5 to 10 (depending on memory available) included files,
fixed.
-----------------------------------------------------------------------------
08/08/96 * PPC 1.00 Public Beta 2
Added:
■ ':' may now be used to separate logical lines on a physical
line
■ '$INCLUDE:FILE.PPS & #include file.pps may now be used to include
an external source file.
■ '*' as the first character of a line specifies a comment
■ Note: thanks to CyZ/Peanuts for mentionning the above missing
syntax support
■ Added support of brackets '[' & ']' to retreive a specific
character from a string value! see doc.
Fixed:
■ Error with encoding some small PPE. Fixed. (no compression if no
gain)
-> This happened to 1/5 lines long source codes... :)
■ Added DDATE data type that was missing
-> woops!, one ',' missing! :)
■ Added user variables dependant functions check (getaltuser, ...)
-> I Discovered how easy it was to crash PCB with a PPE compiled with
PPLC...
■ Fixed compiling of statement VarAddr
■ Fixed compiling of statement Bitset & Bitclear
■ Autodetection of crypting method disabled the -feN switch, fixed.
■ Fixed bug in autodetection of crypting method. 3.20 had the
crypting method of 3.30 if autodetection on
■ Fixed check of dimentions number. It was possible to assign an
array without specifying subscripts.
