Change file content based on data
I have a Transaction File coming into the system. In this file, in all records the relevant data is as follows-

Position 1:10 -> Transaction Code
Position 252:255 -> 4 digit business code

Now based on these 2 fields I have to alter value in Transaction code (Position 1:10)
Code:
For example if  10 digit transaction code is “CN0001N  -“  and 
4 digit business code is one of following values  0292, 0379, 1038, 7810, 7811, 7812, 7842, 7843 
change the 10 digit transaction code to “CNQCSHN  -“



I have to check for 15 similar conditions.

Also My file is having lots of records - (Around 1 Million) so performance is also an issue.

Could someone please suggest the approach which should be taken for this?

mdbfontencoding

mdbFontEncoding(5)						 The m17n Library						mdbFontEncoding(5)

NAME

       mdbFontEncoding - Font Encoding

DESCRIPTION

       The m17n library loads information about the encoding of each font form the m17n database by the tags <font, encoding>. The data is loaded
       as a plist of this format.

       FONT-ENCODING ::= PER-FONT *

       PER-FONT ::= '(' FONT-SPEC ENCODING [ REPERTORY ] ')'

       FONT-SPEC ::=
	   '(' [ FOUNDRY FAMILY
	      [ WEIGHT [ STYLE [ STRETCH [ ADSTYLE ]]]]]
	    REGISTRY ')'

       ENCODING ::= SYMBOL

       FONT-SPEC is to specify properties of a font. FOUNDRY to REGISTRY are symbols corresponding to Mfoundry to Mregistry property of a font.
       See m17nFont for the meaning of each property.

       For instance, this FONT-SPEC:

	   (nil alice0 lao iso8859-1)

       should be applied to all fonts whose family name is 'alice0 lao', and registry is 'iso8859-1'.

       ENCODING is a symbol representing a charset. A font matching FONT-SPEC supports all characters of the charset, and a character code is
       mapped to the corresponding glyph code of the font by this charset.

       REPERTORY is a symbol representing a charset or 'nil'. Omitting it is the same as specifying ENCODING as REPERTORY. If it is not 'nil', the
       charset specifies the repertory of the font, i.e, which character it supports. Otherwise, whether a specific character is supported by the
       font or not is asked to each font driver.

       For so called Unicode fonts (registry is 'iso10646-1'), it is recommended to specify 'nil' as REPERTORY because such fonts usually supports
       only a subset of Unicode characters.
