Appendix K Example fhconvert Parameter File
This example of an fhconvert parameter file is used to convert a relative
file to a C-ISAM file.
All parameter records and their specifications may be in either upper or
lower case (except path and file names which are case sensitive). Tab
characters and spaces are totally interchangeable. There is no
significance in the order in which the parameters are written.
# parameter file for convert relative file to an indexed file
# input parameters
IN rel-file # input file name
IT R0 # input file type - relative
ID 0 # LF record delimiter
IF 240 # fixed record length
# Output parameters
ON /pathname/isam-file # output file name
OT I0 # output file type - C-ISAM
OV 200/240 # Variable record length 200 min/240 max
OB 511 # block size (optional)
PK D(129:29:Chartype) # Prime key description
# key can have duplicates
# start byte is 129
# key length is 29
# key type is CHARTYPE
AK C (160 4:CHARTYPE) # Alternate key description
# key has compression
# start byte is 160
# key length is 4
# key type is CHARTYPE
AK (164:10*CHARSIZE:CHARTYPE) # Alternate key description
# start byte is 164
# key length is CHARSIZE*10
# key type is CHARTYPE
DC 001 # data compression type 1 for
# output ISAM file
# (This will automatically
# change OT from I0 to I3)
