ISAMIO.EXE converts ISAM database tables to ASCII text files, or ASCII text
files to ISAM database tables.
ISAMIO {option1} asciifile databasename tablename specfile {option2}
■ option1 One option from the list below must be specified:
Option Description
═══════════ ═══════════════════════════════════════════════════════
/? or /H Displays help for the ISAMIO utility; anything following
these options on the command line is ignored
/E Specifies ASCII text file to create from ISAM table
/I Specifies ISAM table to create from ASCII text file
■ asciifile Name of ASCII file to import (/I) or export (/E)
■ databasename Name of database into which the table should be
placed (/I), or from which the data for the ASCII file
should be taken (/E)
■ tablename Name of table within database file into which records
from the ASCII file should be placed (I), or from which
the data for the ASCII file should be taken (/E)
■ specfile Required only when converting Btrieve files:
basictype, size, columnname
• basictype Term used by Btrieve to identify the
data type
• size Length of field in the Btrieve format;
size is ignored for all types except
STRING
• columnname Any valid ISAM column name
■ option2 You can specify /A or /C but not both; /F is always
optional:
Option Description
═══════════ ═══════════════════════════════════════════════════════
/A Specifies that data being imported (/I) should be
appended to tablename. If tablename does not exist, an
error message is displayed. If /A is not specified,
ISAMIO imports the data into the named table based on
the table description given in specfile. If no specfile
is named (or found), an error message is displayed.
/C When an ISAM table is being imported (/I) from an ASCII
file, /C specifies that the table's column names should
be taken from the first row of data in the ASCII file;
if omitted, ISAMIO interprets the first row as the
beginning of data records and looks for column names in
specfile.
/E When an ISAM table is being exported (/E), /C specifies
that the table's column names should appear in the ASCII
file as the first row of data; if omitted, column names
are not exported.
/F[: width] Stipulates the size of fixed-width fields in the data
being imported (/I) or exported (/E); if omitted, fields
are assumed to be comma-delimited. Note: When exporting,
width specifies the width of binary fields; the default
width is 512.
