Text Appearing Before Image:
e repositioned atthe beginning of the file. The form of the statement is For ASCII filesREST0RE #file designatorwhere the file designator is as previously described. For binary filesREST0RE: file designator In addition to repositioning the data pointer, the RESTORE statement resets a sequential fileto the read mode. This makes it possible to read a file that has been previously written by thesame program, or to read the file more than once during a program run. The only action takenon a random binary file is the repositioning of the data pointer. In the following example. Line 40 will read the same values from the file DATA that were readby Line 20. Line 30 sets file B to the read mode and the data pointer at the beginning of thefile. Caution: If the last access to the designated file, prior to execution of the REST0RE state-ment, was with a READ statement, an INPUT statement, issued subsequent to the REST0REstatement, will begin reading data from the second line of the file. Example:
Text Appearing After Image:
74 SCRATCH Statement Sequential files specified in a program are initially opened in the read mode. Before you canwrite to a sequential file, it must be placed in the write mode. This can be done with theSCRATCH statement. Valid forms of the statement are For ASCII files por binary files SCRATCH # file designator SCRATCH: file designator where the file designator is as previously described. When a file is scratched, all data elementscontained in the file are erased. If SCRATCH is used with a random binary file, the data pointer is positioned at the beginning ofthe file, and all data elements are replaced with binary zeros. DELIMIT Statement The standard file delimiter used to separate items when reading from or writing to an ASCII fileis the comma. Sometimes it may be useful to have a nonstandard file delimiter. The DELIMITstatement allows you to specify such a nonstandard delimiter. Valid forms of the statement are DELIMIT #file designator, (character) DELIMIT #file designator:(chara
