|
# This function pads a string on the left side with a specified character to

# reach the specified length. If the string length is already long enough or
|
|
# longer, the string will not be modified.

# PAD_STRING(OUT_VARIABLE DESIRED_LENGTH FILL_CHAR VALUE)
|
|
#
|
|
# OUT_VARIABLE: name of the resulting variable to create
|
|
# DESIRED_LENGTH: desired length of the generated string
|
|
# FILL_CHAR: character to use for padding
|
|
# VALUE: string to pad
