The String Pool is a Read Only, Word indexed Array created by the Algol Compiler to contain constant string values.

		(01,0004) = POOL DATA DESCRIPTOR    

 	000C (01,0004)  5 080000 C40004  Desc: Untouched, Length=12, Readonly (Codefile address=4)

 	000B (01,0004)  C A80000 001DD9 Desc: Present-mom, ASD=00EECD, Length=12, Readonly 

Each string in the String Pool starts on a Word boundary, and the com piler generates a word index for each logical string.

		0003:0005:3  INDX               A6 

The compiler modifies the generated descriptor size when indexing a Hex String constant.

This code sequence was generated by the Algol Compiler. It references a 25 character Ebcdic String which is located at Word 7 in the String Pool.

A String Pool contains single precision words which contain the string characters. When the absent MOM descriptor for the String Pool is touched, the data is read in from the codefile and stored in an array of single precision (Tag 0) words.

The String Pool can probably be segmented in the same way as a Segmented Value Array.
