Replace line and field using SED and/or AWK or some other suggestion
QUESTION 1:
How do you replace a specific line (i.e. line 4) with a new user defined line (i.e. the contents of SAMS’s name, history, math and English grades have been set already). I have been attempting to use SED (FYI: I don’t have GNU SED) or AWK, but haven’t had any luck. FYI: I am using SOLARIS 10 as an OS. See example below. FYI: KEEP IN MIND FOR ALL EXAMPLES I WAS UNABLE TO PROPERLY ALIGN NAME, HISTORY, MATH AND ENGLISH WITH THERE CORRESPONDING VALUES USING THIS THREAD WORD PROCESSOR .
Below is the starting file.

NAME: HISTORY: MATH: ENGLISH:
ROB A B A
DAN A C B
JOHN C B A

For example if John has left the class and SAM has joined and his grades are all A's.
Resulting file (BOLD TEXT IS WHAT NEEDS TO CHANGE):

NAME: HISTORY: MATH: ENGLISH:
ROB A B A
DAN A C B
SAM A A A





Question 2:
Does anyone know how to replace a specific field (i.e. line 2, field 2)? I would like to do the replacement this generically (line 2, field 2). So, for example I don’t want to use grep on ROB. Again, I do not have GNU SED. See example below.
Below is the starting file.

NAME: HISTORY: MATH: ENGLISH:
ROB A A A
DAN A A A
JOHN A A A

Resulting file (BOLD TEXT IS WHAT NEEDS TO CHANGE):

NAME: HISTORY: MATH: ENGLISH:
ROB A B A
DAN A A A
JOHN A A A

mfontset_lookup

mfontset_lookup(3m17n)						 The m17n Library					    mfontset_lookup(3m17n)

NAME

       mfontset_lookup - Lookup a fontset.

SYNOPSIS

       MPlist * mfontset_lookup (MFontset * fontset, MSymbol script, MSymbol language, MSymbol charset)

DESCRIPTION

       Lookup a fontset. The mfontset_lookup() function lookups fontset and returns a plist that describes the contents of fontset corresponding
       to the specified script, language, and charset.

       If script is Mt, keys of the returned plist are script name symbols for which some fonts are specified and values are NULL.

       If script is a script name symbol, the returned plist is decided by language.

       o If language is Mt, keys of the plist are language name symbols for which some fonts are specified and values are NULL. A key may be Mt
	 which means some fallback fonts are specified for the script.
       o If language is a language name symbol, the plist is a FONT-GROUP for the specified script and language.  FONT-GROUP is a plist whose keys
	 are FLT (FontLayoutTable) name symbols (Mt if no FLT is associated with the font) and values are pointers to MFont.
       o If language is Mnil, the plist is fallback FONT-GROUP for the script.
       If script is Mnil, the returned plist is decided as below.
       o If charset is Mt, keys of the returned plist are charset name symbols for which some fonts are specified and values are NULL.
       o If charset is a charset name symbol, the plist is a FONT-GROUP for the charset.
       o If charset is Mnil, the plist is a fallback FONT-GROUP.
RETURN VALUE

	   It returns a plist describing the contents of a fontset. The plist should be freed by m17n_object_unref().
