RECFM specification - Key = '0049'

DALRECFM specifies the record format. When you code this key, # and LEN must be one, and PARM contains one of the following values:
X'02'
Machine code printer control characters in record (M), or complete QTAM record (R)
X'04'
ASA printer control characters in record (A), or complete QTAM message (G)
X'08'
Standard fixed records, spanned variable records, or segment of QTAM message (S)
X'10'
Blocked records (B)
X'20'
Variable ASCII records (D), or track overflow (T)
X'40'
Variable records (V)
X'80'
Fixed records (F)
X'C0'
Undefined records (U)
Note: When you code combinations of RECFM values, PARM contains the sum of the values.
Example: To specify fixed records, code:
KEY    #      LEN    PARM
0049   0001   0001   80
Example: To specify variable blocked (VB) records, code:
KEY    #      LEN    PARM
0049   0001   0001   50
