Reading data in from text files

Read data into COST from cost.dat

initializations from 'cost.dat'
  COST
end-initializations

Data file cost.dat (dense data format)

COST : [3.9 0 4.8
        0 7.5 5.5]

Data file cost2.dat (sparse data format)

COST: [("Oil1" 1) 3.9  ("Oil1" 3) 4.8
       ("Oil2" 2) 7.5  ("Oil2" 3) 5.5]

Mosel data format:

file may include single line comments, marked with '!'
format: label, colon, data value(s)
for an array, use a single list enclosed in [ ]
list may be comma or space separated
dense format: the values fill the data table starting at the first position and varying the last index most rapidly
sparse format: each data item is preceded by the corresponding index tuple (in brackets)

Specifying the absolute path

initializations from 'c:/data/cost.dat'
  COST
end-initializations

Path relative to current working directory

initializations from '../cost.dat'
  COST
end-initializations

Read several data tables from a single file

initializations from 'cost.dat'
  SCOST
  PCOST
end-initializations

Different data label and model object names

initializations from 'cost.dat'
  COST as 'COST_DETAILS'
end-initializations

Read several data arrays with identical index sets from a single table

initializations from 'chess.dat'
  [DUR,WOOD,PROFIT] as 'ChessData'
end-initializations
