Hello Stew,

Following may help you in same, following code will check if field 1st is less than 300 then it will print 300 at first field else it will print actual 1st field's values.
Code:
awk '{$1=$1<300?300:$1} 1'  Input_file

Output will be as follows.

install-datebook

install-datebook(1)					      General Commands Manual					       install-datebook(1)

NAME

       install-datebook - installs a new datebook entries onto your Palm handheld device

SYNOPSIS

       For serial devices, the -p <port> option is required, or you may use the $PILOTPORT environment variable:
       install-datebook -p /dev/ttySX filename [filename filename ...]

       For USB devices, the new USB port specification is:
       install-datebook -p usb:/dev/ttyUSBX filename [filename filename ...]

DESCRIPTION

       install-datebook allows the user to write one or more datebook entries from one or more source files. Once install-datebook is started, the
       user must invoke HotSync on the target device by pressing the HotSync button on the cradle or by tapping on the HotSync icon  in  the  Palm
       launcher.

       The  format  of	the source file contains one datebook entry on line, containing four tab separated fields. The fields are start date/time,
       end date/time, alarm settings, and the description of datebook entry. This program doesn't yet support repeted entries. The date  and  time
       must be in format understand by parsedate.y. At the very least, the following two formats are understood:

       August 11, 1997 0800 GMT+300
       1997/08/11 08:22:33 GMT+300

       If  either  one	of  the  date  and  time  fields  is empty, the entry is installed without time. If the alarm field is empty, the entry is
       installed without setting any alarms. The alarm field can contain numbers followed by "m" (minutes), "h" (hours), or "d" (days).
       Here are some example lines ("<TAB>" = tab, "<NL>" = newline in these examples):

       -> 1997/08/11 0800 GMT+300 <TAB> 1997/08/11 0900 GMT+300 <TAB> <TAB> IETF Registration <NL>

       -> August 11, 1997 0900 GMT+300 <TAB> August 11, 1997 0930 GMT+300 <TAB> 2m <TAB> Introductions <NL>

   OPTIONS
       none

USAGE

       The program will connect to the target Palm device, and write the datebook-formatted file given on the command line onto the Palm into  the
       DatebookDB.pdb file.

KNOWN BUGS

       If  no  timezone  is given, install-datebook will assume the time is in GMT and it will convert it to localtime. If you don't want to write
       timezone entries to all begin and end times, set the TZ environment variable to GMT before running this program.
