Assembler as62 (1)
Development Tools
Outline
Converts the mnemonic of the source files into object codes (machine
language) of the S1C62. The results are output in a relocatable object file.
This assembler includes preprocessing functions such as macro definition/call,
conditional assembly, and file-include functions.
Flowchart
Start-up Command Usage
Usage: as62 [options] <file name>
Options: -d <symbol> Add preprocess definition
-e Output error log file (.ERR)
-g Add source debug information in object
-l Output relocatable list file (.LST)
-o <file name> Specify output file name (.O or no extension)
File name: Source file name (.DAT, .S, or .MS)
