SPFLite - V3.0.24069 2024-03-09

num-var = SPF_REP(line-ptr, col-num, data-str)

Operands:

line-ptr

the line pointer of the data line to be modified.

col-num

the column number at which the data-str contents are to be replaced.

data-str

the replacement text string

Returns:

Both num-var and RC will be 0 and Msg$ will be "" (Null) for successful completion

Both num-var and RC will be 8 and Msg$ set to an error message on failure (e.g. invalid line pointer)

Special Notes:

Will replace text in line-ptr with data-str starting at the indicated column col-num. Other text in the line is unaffected. If needed, the line's text will be extended with blanks to col-num - 1 before data-str is copied in.

The replacement operation consists of replacing characters from data-str into the same relative location in the line's original text.
