STRING 

STRING <var1[size1]>[,<var2[size2]>...];

STRING <var1[num_elements1][num_characters1]>[, 

<var2[num_elements2][num_characters2]>...];

Declares a string that is local to this SIMPL+ program. Strings are of arbitrary length, 
so a maximum size must be specified. When a STRING variable has new data 
assigned to it, the old data is lost.

When used in its second form, a one-dimensional array of strings is allocated. The 
array has num_elements+1 elements, and num_characters per element allocated. The 
legal indices for referencing the strings are 0 through num_elements.

The value of SIZE and NUM_CHARACTER may be up to 255 in SIMPL+ Version 
1.00. In SIMPL+ Version 2.00 and later, they may be up to 65535. The value of 
NUM_ELEMENTS may be up to 65535.

NOTE: Strings in Version 3.00 for the 2-Series Control Systems may not be passed 
by value to a function. They must be passed by reference.

NOTE: If no Return Value is specified within an String_Function, then an empty 
string (0) will be returned by default.

NOTE: (X-Gen) The values of STRINGs declared are non-volatile. If the system is 
powered down and up, the variables will take on their previous values. If programs are 
changed and uploaded, the values are not preserved.

NOTE: (2-Series) STRINGs can be volatile or non-volatile. The default is defined 
using the compiler directives #DEFAULT_NONVOLATILE or 
#DEFAULT_VOLATILE or overridden using the nonvolatile or volatile keywords.
