SQUOZE Redirected from IBM SQUOZE

IBM's SQUOZE was a representation of a relocatable program object file with a symbol table on punched cards in the SHARE 709 operating system. A program in this format was called a SQUOZE deck.

Identifiers in the symbol table were represented in a 50-character alphabet, allowing a 36-bit word to represent 6 alphanumeric characters plus 2 flag bits, because 506 < 234.

The name SQUOZE was later borrowed for similar schemes used on DEC machines; they had a 40-character alphabet (50 in octal) and were called DEC Squoze or DEC Radix-50.

Etymology

"Squoze" is a facetious past participle of the verb 'to squeeze'.
