FIXSTRING Procedure
Parameters
template input
STRING:ref:*
is the character string to be used as a modification template.
There are three basic subcommands that you can use in
template: replacement,
insertion, and deletion.
In addition, replacement can be either explicit (a subcommand beginning with “R”)
or implicit (a subcommand beginning with any nonblank character other than “R,”
“I,” or “D”). The form of
template is:
template = { subcommand // ... }
subcommand =
{ Rreplacement string } ! replace subcommand
{ Iinsertion string } ! insert subcommand
{ D } ! delete subcommand
{ replacement string } ! implicit replacement
template-len input
INT:value
is the length, in bytes, of the template string.

data-len input, output

data. On return, it
contains the length, in bytes, of the modified data string in

maximum-data-len input
INT:value

data can expand during the call
to FIXSTRING. If omitted, 132 is used for this value.
