RGrow resizes fixed length records e.g. RGrow.exe MyFile.seq 500 600 will grow each record from 500 to 600 bytes by padding binary zeros. Will also truncate records. These are not the old and new sizes of the file, but of the fixed length records in the file. If you increase the record size, each record will be padded with nulls. The entire file will grow as a result. This program may be freely copied and used for any purpose except military. C source included. Works as a Windows Console app from the DOS command prompt.
