**************************************************************************
This patch data file is designed to modify only Rev. #2.00B of PowerBASIC,
both PB.EXE and PBC.EXE.
It provides the following enhancements and/or corrects the following
error conditions:
1. An incompatibility exists with certain .OBJ files, in particular,
those created by the Microsoft Macro Assembler (MASM). An attempt to
$LINK them may generate error 507 - Invalid $LINK file.
2. Sound generation statements (SOUND/PLAY) may cause generation of a
string/array memory corrupt error (error #242). This may become
particularly noticeable during a CHAIN or RUN operation.
3. In emulated float mode, certain error conditions (notably divide by
zero), may cause an incorrect error address (ERADR function) to be
calculated. This in turn, may prevent RESUME <NEXT> from executing
correctly.
4. Execution of a SHELL statement while a communications file is open
may cause generation of a string/array memory corrupt errer (error #242).
