Basically we have ASCII file with numeric data we want to convert that files data to Packed decimal format to send it to main frame.

gmtconvert
GMTCONVERT(l) GMTCONVERT(l)
NAME
gmtconvert - Convert between ASCII and binary 1-D tables
SYNOPSIS
gmtconvert [ inputfiles] [ -H[nrec] ] [ -M[flag] ] [ -V ] [ -: ] [ -bi[s]n ] [ -bo[s][n] ]
DESCRIPTION
gmtconvert reads its standard input [or inputfiles] and writes out the information to standard output. Its main purpose is to convert
between binary and ASCII data tables. Input (and hence output) may have multiple subheaders if -M is selected.
datafile(s)
ASCII (or binary, see -bi) file(s) holding a number of data columns.
OPTIONS
-H Input file(s) has Header record(s). Number of header records can be changed by editing your .gmtdefaults file. If used, GMT default
is 1 header record.
-M Multiple segment file(s). Segments are separated by a special record. For ASCII files the first character must be flag [Default is
'>']. For binary files all fields must be NaN.
-V Selects verbose mode, which will send progress reports to stderr [Default runs "silently"].
-: Toggles between (longitude,latitude) and (latitude,longitude) input/output. [Default is (longitude,latitude)]. Applies to geo-
graphic coordinates only.
-bi Selects binary input. Append s for single precision [Default is double]. Append n for the number of columns in the binary file(s).
-bo Selects binary output. Append s for single precision [Default is double].
EXAMPLES
To convert the binary file test.b (single precision) with 4 columns to ASCII, try
gmtconvert test.b -bis4 > test.dat
To convert the multiple segment ASCII table test.d to a double precision binary file, try
gmtconvert test.d -M -bo > test.b
