Entab - Function Summary

Summary:

Converts spaces in a string to tabs. (tab size 4)

Usage:

entab string

Arguments:

string - The string argument. (must be: any-string)

Refinements:

/size - Specifies the number of spaces per tab.

number - The number argument. (must be: integer)

Description:

probe entab text
{^-^-no
^-^-tabs
^-^-in
^-^-this
^-^-sentence
}

probe detab text
{    no
    tabs
