What is a SEM file?
Memo file created by Alpha Five, an IDE that enables users to develop Web, desktop, and mobile applications; contains data in the memo format, which is the same format used by .FPT and .DDM files; includes design information and code for any objects, reports, and forms attached to the set; created along with .SET and .SEX linked set files.
When two or more tables are linked together in Alpha Five, a set, which consists of a SEM, SET, and SEX file is created. These files make up the set data dictionary for the two or more tables linked together. The dictionary stores reports, forms, and any other objects linked to the set. SEM files should be kept with the SET and SEX Set Data Dictionary files in order for Alpha to find all of the elements and their pieces.
SET files are similar to .DBF files because they have a width limitation for how many characters can be held within a column. So Alpha Five creates a ten character field in SET files that references the memo location in the SEM file that contains the actual information.
NOTE: In 2013, Alpha Five became Alpha Anywhere.
