#READ( symbol )
| #READ | Reads the next record from the opened read-only file. |
| symbol | The symbol to receive the text from the file. |
The #READ statement reads the next record (up to the next CR/LF encountered) from open read-only file. The symbol receives the text from the file. If the last record has been read, the symbol will contain a value equivalent to the %EOF built-in symbol.
Example:
#OPEN(%ProgramFile),READ #!Open it in read-only mode
#DECLARE(%ASCIIFileRecord)
#LOOP
#READ(%ASCIIFileRecord)
#IF(%ASCIIFileRecord = %EOF)
#BREAK
#ENDIF
#! Parse the line and do something with it
#ENDLOOP
#CLOSE(%ProgramFile),READ #!Close the read-only file
