CONVERT
EXCHG

Syntax: CONVERT src_file,dst_file,original$,replacement$
   and: EXCHG device_file,old$,new$
Location: CONVERT (CONVERT) and ATARI_REXT (EXCHG)

CONVERT will copy src_file to dest_file and replace all occurrences of original$ by replacement$.

EXCHG is similar, except that it changes the original file (rather than creating a copy).

Both  strings  must  have the  same  length.
The search is case-independent.
No default devices are supported.

NOTE:
The character CHR$(0) cannot be replaced.
