I/O formatting Edit descriptors A and R (character) edit descriptors The A and R edit descriptors define fields for character data. The A edit descriptor specifies left-justification, and the R edit descriptor specifies right-justification. The R edit descriptor is an <strong>HP</strong> extension. The syntax for the character edit descriptors is: [r]A[w] [r]R[w] where: r is a positive integer constant, specifying the repeat factor. w is the field width. If w is not specified, the default is the length in bytes of the corresponding I/O list item. As a portability extension, the list item can be of any data type. When the A and R edit descriptors are used for input and output, the results can differ accordingtowhetherthewidth(w) specified for the edit descriptor is less than, greater than, or equal to the length of the I/O list item. The results on input are summarized in Table 9-3; the results on output are summarized in Table 9-4. Table 9-3 Contents of character data fields on input Descriptor 210 Width/length relationship Result A width < length Data is left-justified in variable, followed by blanks. width >= length Data is taken from rightmost characters in the field. R width < length Data is right-justified in variable, preceded by nulls. width >= length Data is taken from rightmost characters in the field. Chapter 9
Table 9-4 Contents of character data fields on output Descriptor Width/length relationship Result A width length Output the value, preceded by blanks. R width length Output the value, preceded by blanks. I/O formatting Edit descriptors Examples of the use of character edit descriptors on input are provided in Table 9-5. In the table, b represents a blank and z represents a Null.
