replace tabs by blanks
 
Description

s2 detab(s1, i1, i2, ..., in)
detab(s1, i1, i2, ..., in) produces a string based on s1 in which each tab character is replaced by one or more blanks. Tab stops are at i1, i2, ..., in, with additional stops obtained by repeating the last interval.
 
Parameters
s1
string containing tabbed data
i1…
integer tab values
returns
string with tabs replaced by blanks to pad out the data into columns
 
Defaults
i1
9
 
Errors
101 i1, i2, ..., in not integer
103 s1 not string
210 i1, i2, ..., in not positive or in increasing sequence
