- 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
- ------ ------------------------------------------------------------------------
-
- 3.10A New ELSE command
- Allows BEGIN/ELSE/END blocks
- New READNEXT command
- Reads next line from input file, maintaining current place in POM file
- New SETLEN command
- Sets a variable to the length of a value (e.g. "XYZ" is length "3")
- New DONE command (useful only in BEGIN/ELSE/END blocks)
- Jumps to the end of the POM file; equivalent to IGNORE "X" = "Y"
- New ~ comparator ("does not contain")
- PARSE returns a null value if given impossible parsing task
- Example: PARSE x "FRED/MARY" "1*/" "2*/" (problem: no second slash)
- Maximum number of variables and literals increased to 1000 (was 225)
-
- ------ ------------------------------------------------------------------------
- VER. ENHANCEMENTS IN PREVIOUS VERSIONS
- ------ ------------------------------------------------------------------------
-
- 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.
