■ There are too many string variables for the amount of memory
  available. Strings compete with other types of program data
  for memory.
 
■ Possible solutions:
 
  • In the programming environment, unload any documents,
    source files, or include files you don't need.
 
  • The "Out of string space" message occurs when any one of
    the 64K string segments is filled or when Visual Basic
    cannot increase the segment size to 64K. These segments
    and their contents are:
 
    String Segment       String Contents
    ══════════════════   ═════════════════════════════════════
    Module               Module-level string variables
                         Module-level string array elements
                         Procedure-level static string
                         variables
                         Procedure-level static string array
                         elements
                         Named COMMON string variables
                         Named COMMON string array elements
    COMMON               Strings in unnamed COMMON
                         String array elements in unnamed
                         COMMON
    Local string         Procedure-level local string
                         variables
                         Temporary strings
    Local string array   Procedure-level local string array
                         elements (1)
    ──────────────────────────────────────────────────────────
    (1) Note: There is one local string array segment per
    procedure. It is allocated when the procedure is invoked
    and released when the procedure is exited.
 
  • Find out which of the above string segments is filled by
    using FRE(string variable). This returns the amount of
    string space left in the segment where the string variable
    is located.
 
  • If one segment is filled, you can free up space by moving
    a string from the filled segment into another segment.
    For example, if the module segment is filled, you can
    change a module-level string to a string in unnamed
    COMMON.
