Description
Erases old files and gets enough storage for the assembler to
execute in.
Entry point for the ASM3705 command processor.
Calls the 3705 Assembler (IFKASM). Issues FILEDEFs for the necessary assemtler files.
Returns control to CMS. Checks that the input file exists.
If running in a batch machine, sends ASSEMBLING filename A1
message.
Finds a read/write disk for writing text and listing files.
Closes the output files and erases the utility files.
Checks the format of the input file.
