File

Files are either OLD (for input) or NEW (for output). They can be in HAR or various text formats. The name of the file (below: IO, PARAMS, SUMMARY, TABLE, and so on) is a logical name, not the name of a file on disk. The connection between logical files and the actual names of files on disk is made at run-time, using a CMF file.

File IO # Input-output data # ; ! input header !

File (old) PARAMS PAR79.DAT # parameters # ;

! above practice (naming actual file) is NOT recommended !

File (new, text) SUMMARY ;

File (text,new,spreadsheet,separator=";") TABLE ;

File (for_updates) IO_UPDATED #to contain updated prices# ;

File (new, gams) WOTAWASTE ; ! write data in GAMS format !

File qualifiers are:

OLD or NEW or FOR_UPDATES (OLD is the default, FOR_UPDATES is provided to declare a new logical file which can have updated values written to it)

HEADER or TEXT or GAMS (HEADER, ie HAR, is the default)

For TEXT files only:

ROW_ORDER or COL_ORDER or SPREADSHEET (ROW_ORDER default)

For SPREADSHEET files only:, SEPARATOR = "<character>" (comma is default)

New for GEMPACK 9.0

File (new, text, SSE) SUMMARY ; ! labelled spreadsheet format !
