Text Justification

If the justification mode is ASIS, the string is moved directly to the input variable unchanged. If the presentation space is larger than the variable, then no truncation is performed and the field is flagged as error (overflow). If the presentation space is smaller than the variable, then the variable is aligned left and filled with spaces.

For all other types of justification, the value in the text field is left-aligned. If the variable exceeds the size of the presentation space and significant data would be truncated, the field is flagged with an overflow error.
