Simh_tapes Ada Package

Simh_tape is an Ada package for handling magnetic tape images in the standard format used by SimH and many other computer simulators and emulators.

Low-level subprograms include...

• Read_Meta_Data() and Write_Meta_Data() for handling headers, trailers, and inter-file gaps
• Read_Record_Data() and Write_Record_Data() for handling data blocks (without their associated headers and trailers)
• Rewind() and Space_Forward() for positioning the virtual tape image

Higher-level subprograms include...

• Scan_Image() for examining/verifying a magnetic tape image file
• Dump_All_Files() to extract each file found on the tape image as a numbered blob file

An example command-line program is included simhtapetool which uses the package to provide a command line interface for...

• creating a new SimH tape image file (from a simple CSV definition and source files)
• dumping each file found on a tape image to a separate blob file
• scanning the tape image for validity
