The docs say that Generate Digest accepts either a BLOB or a TEXT variable: http://livedoc.4d.com/4Dv15-R5/help/Command/en/page1147.html
The docs also say that both Blobs and Text variables are limited to 2 GB - here are the relevant excerpts: BLOB http://livedoc.4d.com/4Dv15-R5/help/Title/en/page262.html#12745 -------- A BLOB field or variable is a series of bytes (from 0 to 2 GB in length) that you can address individually or by using the BLOB Commands. There is no expression of type BLOB. Note: In the 4D Language Reference manual, BLOB parameters in command descriptions are denoted as BLOB. String http://livedoc.4d.com/4Dv16-R2/help/Title/en/page262.html#1211073 -------- String is a generic term that stands for: * Alphanumeric fields or variables: an Alphanumeric field may contain from 0 to 255 characters (limit set when field is defined). * Text fields or variables: a Text field, variable, or expression may contain from 0 to 2 GB of text.. * Any String or Text expression There is no difference between a string or text variable. You can assign a string to a text field and vice-versa; 4D does the conversion, truncating if necessary. You can mix string and text in an expression. Note: In the 4D Language Reference manual, both string and text parameters in command descriptions are denoted as String, except when marked otherwise. -Tim ********************************************************************** 4D Internet Users Group (4D iNUG) FAQ: http://lists.4d.com/faqnug.html Archive: http://lists.4d.com/archives.html Options: http://lists.4d.com/mailman/options/4d_tech Unsub: mailto:[email protected] **********************************************************************
