- is the 2-digit hexadecimal symbolic GF module number.
- ggggg
- represents bits 8-27 of a GF relative record number as a binary
counter.
- q
- is a single hexadecimal digit that represents the low-order 4 bits of the
GF relative record number as follows:
- Bit
- Description
- 28
- Unit position of the relative record number.
- 29
- Must be 1 to indicate a relative record number.
- 30
- Must be 0.

automatically adjusted to the next lower fullword boundary.
- bytes

X'01'-X'FFF'.
- Note:
- If the number of bytes you specify does not correspond with an even number of

number of lines.
- Type
- specifies which file copy of the record to display:
- R
- displays the prime copy or the duplicate copy.
- P
- displays the prime copy.
- D
- displays the duplicate copy.
- G
- displays the 4-byte pseudo module number and relative record number
copy.
- Note:
- The P and D options are valid only for FARF format addresses.
- Print
- prints the following data:
- R
- prints to an available printer the record at the specified address.
- RC
- prints to the current display device the chain of addresses from the
specified record for a total of 33 chains.
- RCP
- prints to an available printer the chain of records from the specified
record, up to a total of 33 chains.
- Note:
- The PRINT parameter is valid only for FARF3, FARF4, or FARF5 file
addresses.
Additional Information
- Online help information is available for this command. To display
the help information, enter one of the following:

- Enter the ZCSON command to convert MCHR addresses to FARF3, FARF4, FARF5,
or FARF6 format depending on the system migration stage.
