========================== VERSION HISTORY ============================
========================== ============================
===============================================================================
For easy reference, this history is presented in reverse order (most
recent version first). Remember: if you have previously registered
Parse-O-Matic, you are entitled to unlock any new shareware versions
we create for a period of two years. Thus, your small investment in
the initial registration can provide you with a lot of free updates.
Since we do not automatically ship new versions, we encourage you to
drop by our BBS at 514-345-8654 every few months, to see what's new.
+-----------------------------------------------------------------------------+
| |
| Most of the enhancements to Parse-O-Matic are inspired by POM users. |
| We charge a nominal fee for custom work, but we will usually provide |
| a discount if the requirement seems to be beneficial to other users. |
| POM's evolution has been guided almost entirely by our customers. |

VER. WHAT'S NEW IN THIS VERSION
------ ------------------------------------------------------------------------
3.00A New PARSE command
You can now parse free-form data (including comma-delimited files)
New APPEND command
Allows you to concatenate up to four values
Data in output buffer (via OUT) is now flushed at end of input file
You can now use POM to create binary and fixed-record-length files
Varied comparators (equals, not equals, less than, contains, etc.)
Affects the commands IF, IGNORE, ACCEPT, BEGIN, OUT[END]
For example: IF x > y THEN z = "YES"
------------------------------------------------------------
NOTICE REGARDING CHANGES REQUIRED IN YOUR EXISTING POM FILES
------------------------------------------------------------
This notice involves a change in the behaviour of IGNORE and ACCEPT.
With the addition of varied comparators, you may have to change some of
your old POM files. The IGNORE and ACCEPT commands were considered
"true if the string contains the specified text". In other words, they
performed a "contains" comparison rather than an "equals" comparison.
(IF, BEGIN and OUT[END] used an "equals" comparison.) IGNORE and ACCEPT
now default to an "equals" comparison.
There are two situations in which you must modify an IGNORE or ACCEPT:
(1) If you padded the line with "=" (for clarity or aesthetics), yet
you meant "contains", the line should be changed. For example:
IGNORE $FLINE[1 10] = "YES" (old style, using "=" for clarity)
IGNORE $FLINE[1 10] ^ "YES" (new style, using "contains" symbol)
(2) If you omitted the "=" character, and you want to do a "contains"
comparison, you must insert the "contains" symbol:
IGNORE $FLINE[1 10] "YES" (old style, stated tersely)
IGNORE $FLINE[1 10] ^ "YES" (new style, using "contains" symbol)
If you are comparing two strings of equal length, there is no need to
modify an IGNORE or ACCEPT. For example: IGNORE $FLINE[1 3] "YES"
will continue to work properly, since either a "contains" or "equals"
comparison will produce the same result.
