You can use the following parameters in PARSE to define the rules for extracting variable position/length data to %nnn, %nn and %n fixed parsed fields:

• FIXLEN=m: Specifies the length (m) of the fixed area to contain the extracted variable data for this %nnn, %nn or %n fixed parsed field.
• ABSPOS=p: Start extracting data at input position p.
• ADDPOS=x: Start extracting data at the current position + x.
• SUBPOS=y: Start extracting data at the current position - y.
• STARTAFT=string: Start extracting data at the byte after the end of the character or hexadecimal string.
• STARTAFT=an: Start extracting data at the byte after the first character found from a specified alphanumeric set.
• STARTAFT=BLANKS: Start extracting data after the end of the next group of blanks.
• STARTAT=string: Start extracting data at the first byte of the character or hexadecimal string.
• STARTAT=an: Start extracting data from the first character found from a specified alphanumeric set.
• STARTAT=BLANKS: Start extracting data at the start of the first group of blanks.
• STARTAT=NONBLANK: Start extracting data at the next nonblank.
• ENDBEFR=string: Stop extracting data at the byte before the start of the character or hexadecimal string.
• ENDBEFR=an: Stop extracting data at the byte before the first character found from a specified alphanumeric set.
• ENDBEFR=BLANKS: Stop extracting data at the byte before the next group of blanks.
• ENDAT=string: Stop extracting data at the last byte of the character or hexadecimal string.
• ENDAT=an: Stop extracting data at the first character found from a specified alphanumeric set.
• ENDAT=BLANKS: Stop extracting data at the end of the next group of blanks.
• PAIR=APOST: Do not search for strings or blanks between apostrophe (') pairs.
• PAIR=QUOTE: Do not search for strings or blanks between quote (") pairs.
• REPEAT=v: Repeat this parsed field v times.
