Just in case the input file does not start with an "A" record, try
Code:
 awk '/^A/ || NR==1 { if(F) close(F); F=sprintf("%s%d", NAME, ++N) } { print > F }' NAME="File" inputfile

Hi.

Utility csplit was designed for these kinds of tasks, so:
Code:
csplit -k -z data1 '/^A/' '{*}'

produces byte counts and creates files:
Code:
56
56
42
56

xx00  xx01  xx02  xx03

Sample, contents of xx01:
Code:
A387562985749
B893745647875
B394857348957
K734564735644

See man csplit for details.

Best wishes ... cheers, drl
