+# Requesters — EasyRequest, AutoRequest, ASL File Requester
+
+## Overview
+
+Requesters are modal dialog boxes. Intuition provides `EasyRequest` for simple dialogs; `asl.library` provides file/font/screen-mode requesters.
+
+---
+
+## EasyRequest (OS 2.0+)
+
+```c
+struct EasyStruct es = {
+    sizeof(struct EasyStruct),
+    0,
+    "Warning",                    /* title */
+    "Delete file '%s'?",          /* body (printf format) */
+    "Yes|No|Cancel"               /* button labels (| separated) */
+};
+
+LONG result = EasyRequest(win, &es, NULL, filename);
+/* Returns: 1=Yes, 0=Cancel, 2=No (rightmost non-zero, leftmost=0) */
+/* For Yes|No: 1=Yes, 0=No */
+```
+
+---
+
+## ASL File Requester
+
+```c
+struct Library *AslBase = OpenLibrary("asl.library", 39);
+struct FileRequester *fr = AllocAslRequestTags(ASL_FileRequest,
+    ASLFR_TitleText,    "Open File",
+    ASLFR_InitialDrawer, "SYS:",
+    ASLFR_InitialPattern, "#?.txt",
+    ASLFR_DoPatterns,   TRUE,
+    TAG_DONE);
+
+if (AslRequest(fr, NULL)) {
+    Printf("Selected: %s%s\n", fr->fr_Drawer, fr->fr_File);
+}
+FreeAslRequest(fr);
+CloseLibrary(AslBase);
+```
+
+---
+
+## ASL Font Requester
+
+```c
+struct FontRequester *fo = AllocAslRequestTags(ASL_FontRequest,
+    ASLFO_TitleText,    "Select Font",
+    ASLFO_InitialName,  "topaz.font",
+    ASLFO_InitialSize,  8,
+    ASLFO_DoStyle,      TRUE,
+    TAG_DONE);
+
+if (AslRequest(fo, NULL)) {
+    Printf("Font: %s %ld\n", fo->fo_Attr.ta_Name, fo->fo_Attr.ta_YSize);
+}
+FreeAslRequest(fo);
+```
