Description

The MASKLINE assignment statement places the mask line contents in a variable or sets the mask line from a variable. The mask line can contain any characters and serves to initialize inserted lines to the value of the mask line. See the description of templates in Overlays and templates for more information on the setting of a mask line.

Be careful not to destroy a DBCS string in the mask line. If shift-out (SO) or shift-in (SI) characters in a mask line are overlaid through the MASKLINE statement, the result is unpredictable.

Return codes

0: Normal completion
4: Data truncated
16: Variable data truncated
20: Severe error

To set the mask line to place comment delimiters starting at lines 40 and 70:

ISREDIT MASKLINE = <40 '&STR(/*)' 70 '&STR(/*)'>

To set the mask line to blanks:
