I recently needed to right-adjust and zero-fill a four-byte character field containing digits. Does anyone have any ideas?

The code in 3 will take care of what you need. It works regardless of whether the data is left-adjusted, right-adjusted or even stuck in the middle with leading and trailing blanks. It also works if the field is all blanks or has no blanks.

The code in Figure 3 will take care of what you need. It works regardless of whether the data is left-adjusted, right-adjusted or even stuck in the middle with leading and trailing blanks. It also works if the field is all blanks or has no blanks.

Be sure to set the value for Factor 1 (4, in this example) in the second line equal to the length of the field you are processing (FIELD).

The first line determines the position of the last non-blank byte in the field. The second line calculates the number of leading blanks that need to be added in order to right-justify the data. The third line actually inserts the leading blanks, and the last line translates all blanks to zeros.
