A collection of subroutines is provided which makes possible

the conversion of data in one format to either of the other two

formats. Complex calculations can be performed on A/D

inputted information using floating point arithmetic, with

results outputted in any of the three formats. Machine

language and floating point programs can be intermingled by

appropriate initialization and use of the subroutines.

Minimum Hardware:
PDP-8, A/D and/or D/A converter

Other Programs Needed:
23-bit Floating Point Package

(DEC-08-NFPPA-A-PB)

Restrictions:
Can be used in single field as is;

can be modified for multi-field

operation. A/D and D/A formats

must be the same as AD01A and

AA50
