Iomode

Use Iomode to assign a value to the different parameters associated with a sequential file opened by Openi, Openio, or Openo when doing an abbreviation.

These parameter are adxium, adxifs, and adxirs.

Syntax

 Iomode adxifs STRING_EXPRESSION Using [ABBR]
 Iomode adxifs STRING_EXPRESSION Using [ABBR]
 Iomode adxium INTEGER_EXPRESSION Using [ABBR]

• STRING_EXPRESSION is an expression that returns a string value.
• INTEGER_EXPRESSION is an expression that returns an integer value.
• [ABBR] is the abbreviation used by Openi, Openo or Openio.

Examples

 # Read a file with CR+LF separator in ascii format
 # convert it in a file with LF separators in UTF8 format
 Subprog CONVERT (FILE_IN, FILE_OUT)
 Value Char FILE_IN(), FILE_OUT()
 Local Char LINE(250)
# Open the files
 Openi FILE_IN Using [IN]
 Openo FILE_OUT,0 Using [OUT]
# Set the parameters
 Iomode adxium 50                Using [IN]  : # ascii
 Iomode adxium 0                 Using [OUT] : # UTF8
 Iomode adxifs ''                Using [IN]  : # no field separator
 Iomode adxifs ''                Using [OUT] : # no field separator
 Iomode adxirs chr$(13)+chr$(10) Using [IN]  : # CRLF
 Iomode adxirs chr$(10)          Using [OUT] : # LF
# Copy loop
 Repeat
   Rdseq LINE Using [IN]
   If fstat=0
     Wrseq LINE Using [OUT]
   Endif
 Until fstat=0
 If LINE<>"" : Wrseq LINE Using [OUT] : Endif
# Close files
 Openi Using [IN] 
 Openo Using [OUT] 
End

Comments

When opening a file without an abbreviation, the setting of the parameters is done directly by assignment of adxifs, adxirs, and adxium. In this case, the use of Iomode is not necessary.
